Xinfeng Landslide Stability Moses Luding County Town Of Dadu River Bank

Geological disasters mean the destruction to the geologic environment suddenly or gradually and the damage to human life and property because of the geologic process(including the natural and man-made and integrated).As the continuous development of economic construction,human activities continue to expand to mountain area,human encounter more and more landslide problems in the processing of utilizing the nature and transforming the nature.The effects of the landslide disasters expand widely and seriously day by day and worldwide people is now working on the researches of landslide and the prevention projects.In recent years,domestic and foreign researches for the landslide disasters are mainly in the aspects of landslide mechanism,the theories and methods of for landslide stability analysis,the effects of landslide disasters and the Landslide treatment technology.This article mainly has the research to the Xinfeng landslide of lower Dadu River and the stability research for the after landslides with ice slope from macro qualitative judgment and quantitative calculation.The Xinfeng landslide of lower Dadu River and the after landslides with ice slope are located on the left of the main branch of the lower of Dadu River,the depth of the upper water of the dam is 1.4km,the reservoir with full water will do harm to landslide stability,easily causes reservoir to collapse and to reconstruct,moreover there is the emigration occasion for people from the Chesuo dam,the landslide disaster will bring high-speed surge and sludge in reservoir once it happens,and will directly affect the operation of power plants and threaten lives and property of residents on the right bank.Survey results show that Xinfeng landslide and the after landslide with ice "chair-like"boundary have very obvious characteristics,through the qualitative judgments,the Xinfeng landslide keep stable currently,but affect by external factors such high water level causing by the flooding,storm,earthquake and so on,the landslide stability will be decreased and the landslide will be resurrected.In order to study the Xinfeng landslide and the after landslide with ice,this article uses existing exploration data and test data,set physical model,set different physical parameter by calculating it,calculate the stability of the Xinfeng landslide and the after landslide with ice,then design the prevention project based on it to solve this problem efficiently.
