THERMAL PROPERTIES OF UNSATURATEDSOILS FOR GEOTHERMAL BRIDGE DEICING

ABSTRACT
The geotechnical engineer designs with a wide variety of naturally occurring heterogeneousmaterials where the exact numerical values of their engineering properties cannot be assigned.Therefore, performance monitoring during and after construction is critical to evaluate thedesign judgments and, if necessary, update them. Moreover, the urbanization has led to thedevelopment of areas that were previously considered geologically unstable, and this in light ofthe changes in weather patterns mandates improved monitoring. Traditionally, geotechnicalperformance monitoring is done by lateral ground displacement and vertical settlement mea-surements using instrumentation.
However, the reliability of the monitoring is influenced by the extent to which measurementsvary locally within the instrument zone. In highly variable geologic conditions, a large number ofmeasurement points may be required for reliable monitoring. The advancements in the spatialand temporal resolution of satellite-based remote sensing using Synthetic Aperture Radar(SAR) and optical provide a new paradigm for geotechnical performance monitoring in highlyvariable geologic conditions. Also, manned and unmanned aerial platforms offer an opportunityto acquire remote sensing data as the user requires. These remote sensing techniques providean excellent opportunity for engineers to monitor the performance of geotechnical structures incomplex geologic conditions.
