Technology Research Of Prevention On Zhangmu Landslide In Tibet

Ecological protection technique of slope is a new slope protection technique, and it is used widely in some supporting engineering of slope at railway , Hydropower Station and highway. But it is always an important research in the field of geotechnical engineering, because the study is related to many subjects and is not systemic and idiograpHic enough..The thesis takes the zhangmu landslide in Tibet as the study object. Firstly Fundamental characteristics and stability of the zhangmu landslide wasd. According to the shortcomings of engineering measure maintaining slope stability, ecological protect studied thoroughly, Controlling Method of engineering measure maintaining slope stability was referre ion techniques combining Vegetation maintaining slope stability with engineering measure was put forward to prevent and control the zhangmu landslide in Tibet, the mechanism of vegetation maintaining slope stability in theory was studyed, and it was considered that the affection of stability to the slope was owe mainly to the vegetation root system and Hydrological Effects of vegetation, the limitation of vegetation maintaining slope stability was pointed out. Secondly, the basic theory, technology system and ecological protection construction technics was studied . At last, according to the practical situation of the zhangmu slope and the local region , the method of slope protection of thick layer base material forestry technics was provided to protect slope ecologically. Factual engineering verified that ecological protection construction technics combining Vegetation maintaining slope stability with engineering measure can effectively overcome the shortcomings of engineering measure maintaining slope stability, it can fully exert landscape and environment effects of vegetation, at the same time , can ensure the stability of slope, the technics is practical in some sense.
