Application of comprehensive geophysical prospecting method in stability evaluation of landslide

Landslide is one of the most serious natural geological disasters. Its production condition is complicated, and it is influenced by various natural geological factors. For its evaluation of stability and selection of treatment scheme, the geophysical exploration method is often used to get the related geological information. In recent years, more and more engineering practices indicate that the single geophysical exploration method has the limitations such as inaccurate and intuitive information. The comprehensive geophysical prospecting method is widely used for its characteristics of comprehensive, rapid and rich information, and it is of great significance to selection of treatment scheme for the landslide. Based on Gaijiayin Mountain landslide on Lanzhou-Chongqing and combined with the landslide survey data, using the high-density resistivity method and the integrated geophysical exploration of the Rayleigh surface wave method the parameters such as velocity and resistivity are obtained, and the scope of the landslide slip surface, depth and sliding are further determined. The deformation, failure, development process and the relevant laws are understood so as to provide powerful evidence for the scheme determination of landslide governance.
