Safety Factor Analysis And Optimization Of Different Retaining Structure Form And High Slope Common Function

When the high-grade highways have been constructed in the bedrock mountainterrain,it will inevitably need to excavate the original terrain.Resulting in the highwayslope instability signs are everywhere.Much of the reason is due to people judge thefailure mode of rock slope inaccurate,as well as the calculation of slope stability is notaccurate enough.It is also because of the joints’stochastic and hidden in the rockslope.So that it is difficult to grasp the sense of management in design,manageinadequate will remain safety problem,manage excessive will result in waste,andsometime are even use the inappropriate management.By this token,the slope stabilityevaluation is the base part of slope management engineering,and objective and accurateevaluation of slope stability is the important part of the success or failure ofmanagement engineering.This paper analyzes the stability of rock slope, First, to yuanmo highwayK301+320~+900located high slope for example, using the finite element strengthreduction for stability analysis and get the failure mode, the paper also analyzes thegeotechnical parameter sensitivity of the landslide, confirm structure surfacegeotechnical parameter for the restricting factors of the slope stability, in rainfallcondition,the overall safety coefficient of the structure constitutes by sand is higher thanthe clay structure surface. The simulation compared through the different slopeexcavation slope and supporting form,use the anti-slide pile and frame beams combinedbolting, supporting structure stress is more reasonable when the pile length of anti-slidepiles is5m, the overall safety coefficient is1.199when the slope overall excavationproportion is1:0.4, the quantities of support and excavation are less than actualquantities. Yuanmo highway rock slope stability research achievements, for theengineering and technical personnel provide the basis to the slope reasonable design,and for the slope harness and environment recover in the same treatment provides thereference significance the future.
