Remote Sensing Study of Sliding Surface of Slopes nearby a Large Tobacco Growing Plantation

Abstract

Objectives: A study of remote sensing detection of slip surfaces on man-made slopes in a natural environment nearby a large tobacco growing plantation. Based on the GPR method, the image characteristics of potential slip surfaces on slopes are analyzed based on the change in GPR wave amplitude caused by the water content of the slip surface. The large granularity and permeability of the spoil allows natural precipitation to continue to infiltrate into the bedrock, and the infiltrated water gradually erodes the spoil and forms a water-rich rubble layer with the easily soluble rock mass, which develops into a slip zone and threatens the stability of the slope nearby a large tobacco growing plantation. By analyzing the magnitude of the remote sensing images, the process of water content changes in the soft fracture zone at the bedrock interface of the slope can be efficiently and accurately understood. Ensured the safe operation of the planted tobacco plantation.
