Research On Stability Analysis And Treatment Technology Of The Impact Deposit Soil Cutting Slope Of SHI Zhong Highway

Imcompact deposit is a prevalent long-term discontinuous plasmodium in southwest of China,this imcompact deposit usually is at the situation of stable,but once this imcompact deposit encounter construction and disturbance ,it will lose its stability and cause destruction.Therefore,it is necessary to pay enough emphasis on the problem of how to keep the stability of the incompact deposit cutting slope.This paper conduct research on the stability and treatment technology of imcompact deposit with complex geology situation cutting slope which is based on the item of construction technology of SHI Zhong highway cutting slope ,some results can be concluded from this paper:①The physical mechanics characteristic of the typical incompact deposit from SHIZhong freeway can be KNown through the large indoor shearing experiment and engineering test statistic analysis,and especially analyses conduct on the water contention and stone contention how to effect the buckling collapse mode and stability mechanism of incompact deposit cutting slope.②Through the engineering geology stability appraise and numerical simulation analysis on the prophase stability of incompact stability conherence cutting slope along the highway, it con provide reliable theory reference on designing and constructing of incompact deposit cutting slope.③Through the field investigation and geologic examination analysis,with the foundation of engineering geology stability appraise of cutting slope,meanwhile considering the practicial engineering situation,there can propose four treatmented technology toward incompact deposit cutting slope:slope cutting,gravity retaining wall,brad,brad together with gravity retaining wall。And orthogonal test analysis conducted on brad shoring structural parameter,the drain design and protective desing of high wall are also summarsinessly reaseached.④Through the numerical simulation of different treatments toward incompact deposit cutting slope the feasibility and rationality of the treatments can be demonstrated,the treatment effect of correlative factors can be discussed,and the treatmented effect can be appraised.The results showed that:four treatments technology all can improve the stress and deformation behavior of the cutting slope,the global stability of the impact deposit cutting slope can be startling increasedThis article has been in the favor of the item of 2006 Transportation Committee of Chongqing Technology Project "SHI Zhong Expressway with complicated geological conditions roadbed construction technology".
