ABSTRACT

The aim of this work has been to update ground surface and rock surface point data sets of the Olkiluoto island. The earlier collection of numeric data and 3-D modelling of the surfaces was conducted in 1995 and included, in addition, the ground water table.

Existing data has been checked and partly replaced by more reliable data. New data of recent surveys has been included and data is now reorganized to offer better usability for various purposes. The work concentrates on the collection and description of the rock surface. The data available on bedrock is sparse and diverse. The work includes data transfers and checks done during 2001 by the same author. All data reported and formally available by the end of2003 has been incorporated.

As a result of work 29300 data points of ground surface and 20800 points of bedrock surface has been compiled into text-formatted tables. Also limited versions with varying delimiters have been made available to fit the needs of particular software. The task also tries to demonstrate how data should be used to get best results and how to recognise the reliability of data in practical use.

Ground surface can be represented with reasonable accuracy. Rapidly changing variation in elevation point out sparse data of the rock surface in certain sub areas.

Keywords: Digital terrain model, topography, ground surface, rock surface.

TIIVISTELMA

Tyon tavoitteena on ollut taydentaa maan pinnan ja kallion pinnan pisteaineistot Olkiluodon saarelta. Aiempi numeerisen pisteaineiston ja pintojen mallien luonti tapahtui v. 1995 ja silloin aineistoon sisaltyi lisaksi myos pohjaveden pinnan tason pisteisto.

Olemassa ollut data on tarkistettu ja osin korvattu luotettavammilla aineistoilla. Kokonaan uutta dataa on tullut lisaa ja data on organisoitu uudelleen ajatellen parempaa kaytettavyytta eri tarkoituksiin. Tyo on keskittynyt kallion pinnan tietojen keruuseen ja kuvaamiseen. Kallion pinnasta oleva tieto on harvahkoa ja vaihtelevaa laadultaan. Tyo sisalsi myos osuudet jotka tekija on laatinut v. 2001. Kaikki raportoitu and statukseltaan hyvaksytty aineisto vuoden 2003 loppuun asti on kaytetty.

Tuloksena maan pinnasta on mukana 29300 pistetta ja kallion pinnasta 20800 pistetta. Nama on koottu muotoiltuihin tekstitaulukoihin. Datan muotoiluja on laadittu eri erotinmerkein myos ohjelmakohtaiseen kayttoon. Raportti pyrkii myos osoittamaan kuinka dataa voi kayttaa parhaan lopputuloksen saavuttamiseksi ja kuinka kaytossa huomioidaan vaihteleva datan luotettavuus.

Maan pinnan vaihtelu voidaan esittaa hyvalla tarkkuudella. Nopeat vaihtelut maanpinnan korkeusmallissa osoittavat kallion pinnan aineiston harvuutta tietyilla osaalueilla.

1 INTRODUCTION

The final disposal of the spent nuclear fuel in Finland is managed by Posi va Oy, which is jointly owned by the Finnish power companies Teollisuuden Voima Oy and Fortum Power and Heat Oy. Research for the building of the final disposal facility has been going on for two decades. The Finnish parliament ratified 18.5.2001 a policy decision for a construction licence to build a final disposal facility for the spent nuclear fuel at Olkiluoto area in Eurajoki. This work is part of the site characterisation programme conducted by Posiva Oy.

During 1995 Fintact Oy collected consistent topographical and rock surface data for map production and 3-D modelling purposes which also included groundwater table. This work presents the revision of the point data representing ground surface and rock surface of investigation area of Olkiluoto. Map and a 3-D model of the surfaces can be created based on this data. The most important content of tables is z-value describing elevation in the area. There is much more information on ground surface than on bedrock surface. The data from the bedrock surface is sparse and unevenly distributed. All available directly observed data and partly also interpreted material has been included to the listings and figures of this report. Describing keys have been added to enable different kinds of groupings later on and estimation of data reliability.

Coordinates used in the tables are: first column easting (geographic y-coordinate ), second northing (geographic x-coordinate), and third z-coordinate, positive upwards. Units are meters and delimiters are exchangeable. Basically all reported point data until end of 2003 is included.

The work was commissioned from Posiva Oy, purchase orders 9683/01/LIW and 9582/04/AIK. Liisa Wikstrom and Antti Ikonen from Posiva Oy have been the contact persons, respectively.

2 GROUND SURFACE (TOPOGRAPHY) DATA

Ground surface model contains points from the model created 1995 (Lindh & Saksa) and material created originally by Autio & Hakanen (1991). Discrete points from various surveys have been maintained and was kindly provided by Kari Forsti (from Saanio & Riekkola Oy).

Data is presented in the Table 1 and it shows labels of 13 data blocks making up ground surface data. Contents of data blocks are presented in Appendices 1 -11. Source of data or its closest equivalent is mentioned along with the working report reference. Drawing number which also serves as a key to the data in the table is related to report by Lindh & Saksa (1995) with the same contents. Topography model created during 1995 describes whole area of Olkiluoto island and has been included as it is. It has 11329 points in bounding box east 1522500- 1527000, north 6791000 - 6794000. Data had been selected from much larger, irregular raw data set (more than 600000 points), mostly to compress the file size and simultaneously keeping acceptable accuracy. It has points approximately in 35 meter grid. This point set can be considered as basic ground model and can be used in most cases with or without other data, except in detailed map and modelling needs.

Detailed model contains original 10 meter grid points and is limited to smaller area of east 1525000-1526850, north 6791350-6792900. Detailed area model includes a separate set of 29016 points and produces more detailed surface of main investigation area and in the vicinity of ONKALO.

Year 1995 model has been supplemented by adding new investigation points. Core drilled boreholes presented at spreadsheet 'Ol_koordinaatit_03022004.xls' were added, last borehole included is KR28B, along with percussion drilled boreholes, multilevel piezometers, shallow core drilled holes, perforated stand pipes, seismic shot points, control points, core drilled boreholes made by IVO in the 1970s and test pits.

As a final result the surface data implemented to file, G 1.dat covers following area: 1522500 < Y < 1527224.86, 6791010 <X< 6793980

Data priorities should be taken into account. In the file G 1.dat data is organized so that least reliable data (now from Lindh & Saksa 1995) comes last in order and will be skipped by more reliable points. With a neighborhood diameter of 1.0 meter 14 of 11650 original points was skipped in the modelling process with more accurate new values. Appendix 12 shows G l.dat rendered with elevations exaggerated and scaled 10 times higher.

In case a smaller area is needed a detailed model should be considered. This data set has been produced to file named as G2.dat and it has 28559 points within area: 1525000 < Y < 1526850, 6791350 <X< 6792900

With 1.0 meter neighborhood diameter 16 points were skipped.

3 DATA FROM ROCK SURFACE OF OLKILUOTO

Rock surface data set contains now 19954 points instead of 4100 points covered by previous year 1995 work. New data raised mainly from seismics done during 1970. Part of the seismic data was re-interpreted recently and rock surface as interpreted data is subject to errors (accordingly). Also new boreholes and new geological survey trenches have provided corresponding data sets. Every data point has an attached key and a describing word along with it. Key is a text label referring to a CAD drawing where it is represented, for instance '4.1.27' in this report. Report name is also saved along with every data point if it has been made available. Drawing numbers try to mimic those used in work report 95-03 (Lindh & Saksa) to keep them comparable.

Data is presented following table and it shows names of 25 blocks making up bedrock surface data. Direct source is mentioned along with closest related working report. For every block of data appendices 13 - 37 visualise spatial distribution of data and can be used to assist in individual needs.

Survey data has been taken from spreadsheet 'Ol_koordinaatit_03022004.xls', last borehole is KR28B, along with percussion drilled boreholes, multilevel piezometers, shallow core drilled holes, perforated stand pipes, seismic shot points, control points, core drilled boreholes made by IVO during the 1970s and test pits. Portion of data is new and some has improved correctness due to reproduced measurements.

Data includes material which is of interpreted or estimated type. Coordinates of outcrop points, for example, contain ground model elevation (x and y) connected to each of them (drawing 4.1.2). Points based on ground penetrating radar (4.1.9) and refraction seismics (4.1.19, 4.1.20, 4.1.22) do also contain some uncertainty. Calculated values of sea bottom (4.1.10, 4.1.15), outcrop areas (4.1.11) and Ulkopaanniemi (4.1.24) are included only to give best estimates of bedrock surface when actual data near-by is not available. Inclusion of interpreted data is also intended to correct situations when rock surface tends to artificially become visible above ground surface and real rock surface data is missing.

Sea bottom areas surrounding Olkiluoto island contain 11255 points most of them located outside area of immediate interest ( 4.1.15). Data was equipped with a label describing bounding coordinates to help to extract significant points:

Following codes have been added to data point sets to indicate subareas which they cover. The code attached allows easy selection of subareas as follows: Code #0: all points outside area with codes #1 or #2 Code #1: area inside rectangle 1522000, 6790000- 1529000, 6795000 Code #2: area inside (innermost) rectangle 1522500, 6791000- 1527000, 6794000

In the summer 2001 refraction seismic surveys were made within area 1525200 ... 15265500 and 6791850 ... 6792950 which produced additional 1960 interpreted points to model (drawing 4.1.19). Points were gathered from drawings made by Suomen Malmi Oy (Ihalainen & Lahti 2002) and depicted in Appendix 38.

Additional 2496 points were taken from earlier seismic refraction data re-assessment (Lehtimaki 2003) (Appendix 32, drawing 4.1.20). Data includes following surveys:

survey MTI-8731.40, IVO, 1973, lines 301_302- 311_312 survey 6119, Geotek Oy, 1975, lines 401_ 402- 427 _ 428 survey 6154, Geotek Oy, 1978, lines Y_ 4435- Y_ 4750b survey 9501, Geotek Oy, 1973, lines IA- XXIX survey 7777, Suunnittelukeskus, 1980, lines A-A-L-L survey, Suomen Malmi Oy, 2001, lines 1-27

During the spring 2001 accurate model of rock surface was made from local area in Fintact to TVO concerning Ulkopaanniemi VLJ-site visualisation purposes. Rock surface was modified by pressing points appearing above ground surface one meter below it (Appendix 36, drawing 4.1.24 ).

4 CONCLUSIONS

The aim of this work was to update bedrock surface and ground surface data sets of the Olkiluoto island. The earlier 3D surface models included also the surface of ground water table but at this time this surface has not been re-assessed.

Existing data has been checked and partly replaced by more reliable data. Totally new data of recent surveys has been included and data is now reorganized to offer better usability for various needs. The work concentrates on data from the bedrock surface. The data available on bedrock is getting more well covering. The work includes transfers and checks done 2001 by the same author. All data available by the end of 2003 is presented.

As a result of work 29300 points of ground surface and 20800 points of bedrock surface were entered in text-formatted tables. Also versions with different delimiters are available.

Ground surface can be represented with reasonable details. Model from 1995 has been upgraded with reliable points. Main difference is improved accuracy when dealing with survey points. Also dense grid on ONKALO area gives better model.

Accuracy of the new interpolated topography surface model has been tested in several ways and here z-values of starting points of 28 core drilled boreholes have been calculated from older 1995 version triangulated model. When using points of 1995 model data, maximum variance from measured value is 1.57 meters and average 0.22 meters. With current, more detailed model maximum variance is 1.15 meters and average 0.18 meters.

Bedrock surface model has got plenty of new data but sometimes the local variation in elevation makes the rock surface to behave in non-logical manner.

As an output of work simple text-formatted files are produced and they can directly imported by numerous applications. With semicolon delimited G 1 and R1 models example plots with Surpac were produced, see Appendices 40 and 41.

Comparing rock surface with ground surface gives idea of outcropped areas. In Figure 1 both models are rendered together.
