Enhanced Analysis of Landslide Failure Mechanisms in the Ozark Plateau Region with Electrical Resistivity Tomography
Landslides are a globally occurring geologic hazard that affect infrastructure such as roadways constructed in steep mountainous terrain. In the Ozark Plateau portion of Arkansas, the combination of sloping bedrock, decomposition of shale into high PI clays, and high rainfall contribute to the formation of a significant number of landslides that impact transportation infrastructure. There are currently 175 active landslides affecting roadways in Arkansas. This case history employed electrical resistivity tomography (ERT) across a recurring landslide zone within this portion of Arkansas to characterize the general stratigraphic architecture of the area. ERT surveys conducted across the slide delineated the interface between the shale bedrock and clay layer, and identified highly saturated regions above the clay/bedrock interface. Overall, the addition of ERT data to landslide investigations provides a faster and more cost effective means to develop a detailed subsurface image of the landslide compared to traditional geotechnical instrumentation alone.
