Analysis And Research On East Road Landslide Stability Of The Nanchuan In Xining City, Qinghai Province

Landslide is one of the geological disasters in a multiple, great harm，not onlyto the people’s life threat, but also has large damage to property, environment etc.Therefore, in order to avoid the destruction of the ecological environment andunnecessary losses and waste. This paper in anchuan road landslide in Xining city forthe analysis and the research object, based on full study area landform, formationlithology, geological structure, hydrogeological conditions and human engineeringactivities, through qualitative and quantitative methods of the landslide is studieddeeply, a detailed analysis of its morphology, material composition, and physicalmechanics parameter of rock and soil landslide is determined, analyzed the influencefactors of landslide stability. Master the basic geology, landslide characteristics andlaboratory results, the unbalanced thrust transfer coefficient method, under three kindsof conditions to calculate the Nanchuan Road Development of11landslides stability,results show that in the condition one (Natural) conditions, there are2landslides isstable,4landslides as the basic steady state, there are5landslides in the steady state;in condition two (Natural+Rainfall) conditions, there are2landslide is stable state,there are1landslide is basically stable state, there are2landslide is less stable state of6landslide is unstable; in condition three (Natural+Rainfall+Earthquake conditionsof rainfall), there are1landslide is stable,1landslides in the steady state, there are9landslide is unstable, and based on the analysis of landslide stability and puts forwardpreliminary scheme.
