Application of Electrical Resistivity Tomography and Seismic Refraction Tomography Methods on Landslide Studies: Case Study
The near surface geophysical methods have been extensively used as noninvasive and cost effective methods to characterize the subsurface geological properties since last two decades.Since these approaches are able to illustrate the temporal and spatial changes of geological conditions, they are applied for characterization of landslide zones.The landslide phenomenon is one of the natural disasters which cause life and property losses.The landslide mechanisms are affected by top soil materials, bedrock geometry and subsurface water content.Therefore, the objective of this project is to introduce the different geophysical techniques employed on landslide studies and to analyze their advantages and drawbacks.Also, this paper presents study results of landslide areas located on XiaoShan district in Hangzhou city.The seismic refraction tomography (SRT) and electrical resistivity tomography (ERT) methods were carried out to characterize the landslide of this area.The ERT technique was developed along one line over landslide scar using Wenner configuration.The SRT study was performed along one longitudinal profile coincident with ERT line.The results of combined SRT and ERT have illustrated the layers associated with high water content and clayey soil and geometry of failure surface and the limitations of the methods as well.
