There is a mudstone landslide that poses threat to ramp bridge of Xishan interchange of Xi'an-Baoji Expressway located in Shanxi province, China. This article analyzes the engineering geology and hydrogeological characteristics at first; and then find out that construction loading in the upper of the slope is the main reason for this landslide. Meantime, rainfall and the special geologic conditions of the slope are also two significant contributors to the slide. Landslide thrusts are calculated under natural state (123 kN/m) and saturated state (1645 kN/m) respectively, and used in the analysis of slope stability. A comprehensive treatment with slope cutting, anti-slide pile and drainage is design for the landslide.

Deformation Amount

Deformation amount is depended on area position for approximate condition on engineering geology. Deformation amount is small as radius of curvature become small, conversely large. This paper studies severe plastic deformation reason of slope body. Landsliding reason of the side slope corner area is the rain soaked softening effect for the lower part of the clay rock special slope form. Therefore, abnormal deformation is produced. Slope stability is related slope angle, sometimes related secondary softening effect of rain water. So, key measures of slope safety are ensured for controlling the rain soaked softening effect.
