Investigation of Loess Landslide in Shaanxi by High Density Electrical Method
Release time:
2024-05-25
Due to the complex geological conditions in the landslide, the Wenner device with stable measurement signal and strong anti-interference ability is used. It can be seen from the map that there is low resistivity anomaly in 54-180m in the horizontal direction and 20-40m in the vertical direction. Combined with the landform features of many valleys, loose soil, many saggalls and obvious fissure development in the survey area, it is speculated that it is the saggave anomaly area, where the slope is large, and the overall bedding landslide will occur in case of heavy rainfall or earthquake due to overall instability.
