研究结果表明:采用强度折减法,当坡处于稳定状态时,折减系数增大引起坡变形增大,导致坡体弹性应变能随之增大;但是,坡岩土体能够承受的弹性应变能是有极限的,当折减系数增大到某一值时,坡体的弹性应变能达到极限,再增大折减系数将导致坡失稳破坏;坡体弹性应变能与折减系数服从指数关系;利用弹性应变能与折减系数关系曲线得到的坡安全系数与采用其他经典的方法所得坡安全系数基本一致,弹性应变能随折减系数变化而变化的规律可以作为坡稳定性强度折减法分析的失稳判据。

The presterssed anchor cable frame combined with backwall, drainage is necessary due to longtime sability and permanent utilization.Firstly,according the study of engineering of geology situation of the high slope, the mechanism of deformation failure and the major hazard of the high slope of PanMei is analysed comprehensively.And the whole slope is divided into two different geology enginnering areas:Western slope(1160 section plane -1240 section plane)and Eastern slope(1240 section plane -1320 section plane). The result of 3D numerical simulation is the same as geology judgement. Later,slope cut (1:0.75) is implemented based on the engineering comparison and criterion.Meanwhile, Limit equilibrium method , Monte Carlo Probabilistic slope stability the stability , Sensitivity analysis and Finent element method of for assessing the cutted slope stability is carried out. The result indicates that Western slope is instable, Eastern slope is relatively stable.So much attention should be paid to Western slope.Different reinforcement measures in different areas are given according to its stability and meet economical request.
