Northeast Yunnan Highway Landslide Analysis And Research

In the paper, the shape features,the geological features,the structure features and the seismic effect of landslide on the Long-Dong-Ge expressway are deeply analysed, then the cause of forming landslide is found out. On the basis of the comprehensive analysis to the stability analysis method of landslide, the safe stability coefficient of landslide and the pushing power of landslide are calculated after reasonably determining the shearing strength (value of c andφ). the ultimate conclusion of landslide stability is a large,dynamic and natural soil landslide body. Through the comparing,choosing and optimum analysis of the suitable conditions of many treatment program and measures, the effective harness plan of both slide-resistant pile and drainage system is proposed. In order to secure quality of pile foundation, many testing methods of pile foundation are used adequately. Finally, the landslide is treated both scientistically and environmentally.
