Opis sytuacyjny projektu The railway line Matterhorn Gotthard has a section called Obre-Biel that is beingused by as many as ten passanger trains per hour, along with cargo trains. Overthe years, this section of the railway has been inundated by snow slides andsmaller avalanches. Consequently, railway traffic has been severly impaired andhas also created the danger of possible trail derailment. The line was alsoendangered by rockfalls.
Opis zastosowanego rozwiazania The soution shall protect the railway line against snow slides, snow avalanchesand rockfalls. Choosing flexible rockfall barriers willl decrease the amount oftraffic disturbances.
Standard rockfall barriers are designed to deal with loads caused by rockfalls. So,to serve as a mutli-hazard protection system, some special dimensioning has tobe implemented.
Such special dimensioning is not possible without involving computersimulations. For this purpose, Geobrugg uses finite element simulation softwarecalled FARO. FARO was originally developed by the Swiss Federal Institute forForest, Snow and Landscape Research, and WSL, in order to simulate rockfallbarriers with ring nets.
Further software development financed by the Commision for Technology andInnovation CTI allowes surface load simulations caused by debris flows, shallowlandslides and avalanches.
By using FARO software, a total of 182 meters of rockfall barriers were correctlydimensioned to protect the railway line. They were finally divided into three linesof 112, 42 and 28 meters.
