ABSTRACT
This chapter discusses several research methods, such as numerical simulation, experiment and displacement monitoring of deep hole. In order to make a deep research and analysis on the cause of landslide at K31 section of Changzhi-Jincheng express highway, it provides scientific foundation for control of landslide, and then expected purpose is achieved. The landslide zone with an altitude of 950~1150 m is located in tectonic denudation foothill, which is one wing of an anticline. The bedding landslide usually takes place at the sandwich rock, especially in soft-hard alternating sedimentary rock and happens in one wing of anticline or syncline of weak construction action from the aspect of structure. Human-engineering is the main factor of the landslide form. Since the excavating slope is located at the middle and sub-part of the slope, where the anti-slip action disappears or decreases, it weakens the lock of forepart rock to the whole slope, which easily results in the gliding mass under high potential energy.
