摘要
Wenchuan earthquake has induced many unstable slopes, causing much risk. For removing risk and managing unstable slope, the authors use high density resistivity method to explore the architectural feature of unstable slope. It obtains good geology effect. 2D high density resistivity inversion section chromatogram can reflect the scale, the developmental degree of longitudinal and transverse section, spatial shape. The abnormal shape and characters can reflect overburden thickness, basal layer boundary, water—richen zones, karsts cave and sliding surface. Even it can calculate the amount of fill dam.
