| In recent years, along with the construction in our country mountainous area, appear large number of high slope project problem.both increased the investment,and delayed the time limit forthe project,even creates destruction of the project.The highslope is to change the geologic part to man-made project,its stability is not only controlled by the essential feature of stratum lithology,geologic structure,rock structure,hydrologic geology condition and so on. But also controlled by the artificial transformation degree of dig grade,slope shape,slope ratio and so soil. As a result of the geologic bodys complexity,polytropy and heterogeneity,the design of slope is very complex; Meanwhile as a resuk of geological condition's ever changing.have no slope project to completely apply the experience, this decide the slope question distinctive quallty,and conctete question must have concrete analyse.According to Yunnan Province NanFang Geological Perambulation Parent Companty"Investiqation of Yunnan Dali Lihuaxi residence section ", proceed with progect Geological conditions.Based on Investiqation of Geological information Characters,analys NO.ZK86 slope geological conditions including Stratum, lithology, geologic conformation, weather condition,neotectonics and earthquake are analyzed in this thesis. Landslide formation mechanism, actuality analysis and develop evolvement tide are educed too.Adopt converce-calculation and lab statistics prefercengce.Adpot equatorial plane projection,nstability to ansys stability and have conclution that will slope. According to NO.ZK86 slope,prestressed anchors should be appled at times.This thesis equal attention to the theory and practice.the system summarized the high slope project research primary content and method, and propose a set of systematic research system and the technical route. Chooses the labor spot to is representation,has the llse for reference significance for the similar slope project. |
