通过对二郎山隧道西口引道公路上的榛子林滑坡的地质地貌条件、滑坡体结构及变形破裂形迹的分区特征的调查 ,结合滑坡位移监测资料分析 ,研究了滑坡的成因及近期复活机制 ,并提出了滑坡整治对策

THE GENESIS MECHANISM AND TREATMENT MEASURE OF ZHENZILIN LANDSLIDE IN ERLANG MOUNTAIN

The Zhengzilin landslide is located at the west approach of the Erlang mountain highway tunnel and a revived landslide. According to the geological geomorphic conditions and the stucture of the slidemass, it can be deduced that the old landside was a high speed rockslide formed by bedding slip and bending deformation. The deformation feature and displacement monitoring show that there is a different deformation feature at the defferent position of the slidemass. The revival of the slide was caused by piling up rock fragments of Erlang Mountain tunnel on the slidemass. On the basis of this, the stability and possible destroy way of the slide is evaluated and the treatment measure suggested.
