The application of integrated geophysical method in investigation of the landslide of Taihe-Jinggang Mountains expressway

摘要：

Expressway landslide disaster is a common geological phenomenon.Geophysical methods can be used to study the geological and hydrological environment that caused a landslide,to roughly confirm the scope of the landslide,to make sure the depth and thickness of the slide surface,to determine parameters of a landslide such as geometry,structure,etc.Thus,convincing references can be provided to Calculation of landslides in the Stability and design of governance programs of landsides.In this paper,high density resistivity survey,ground penetrating radar and multichannel Rayleigh wave method are used to study the landslide of Taihe-Jinggang mountains Expressway from K55+ 400 to K55+ 520.By the reasonable Field Employment Method,the scope of the landslide and has been confirmed,the place and depth of the slide interface has been find out.The first stage of the landslide is K55+ 460 K55+510,the depth is 5-7 meters.Above the second stage there has been sliding,the depth of that is 3-5meters.The results can provide important parameters for later comprehensive management of the landslide and have a good geological effects.
