Analysis For Rock Slope Stability Of No.K606 Section Of Tianshan Highway

In the process of transformation of the natural environment,people face a large number of natural and artificial slope safety issues,especially the Slope instability that earthquake induced,all that become a major problem in the infrastructure unavoidably.Because of its complexity and randomness of earthquake and complicated materials,making assessment of slope stability under earthquake it becomes very complicated.Therefore,there is an important significance to have a study on slope stability.Based on available information,here,the seismic instability reliability analysis on rock slop which is located in Dushanzi—Haxilegen Daban Watershed.Since the viscoelastic boundary can simulate ground absorption of scattered waves and recovery performance of soil,so using viscoelastic boundary calculated rock slope seismic stability.The main work is as follows:1.Analysis of slope reliability under seismic loads.And sensitivity analyzes on factors affecting slope stability,including seismic loads.2.Using viscoelastic boundary,By the ANSYS model for time-history analysis under seismic loads,get displacement during the earthquake.3.Reinforcement proposed for analysis conclusion.Ensure the viability of the program.Through analysis and calculation,these conclusions were obtained:1.In its own parameter,the variation of internal friction angle has a more severe impact on the reliability of rock slope.And,we can ignore severe variability in normal stability analysis2.After checking,this paper proposes the method to derive the coefficient of friction is correct.3.Viscoelastic Boundary can simulate actual earthquake ground motion,compared with the fixed boundary,response of the structure is reduced by about 20%.
