摘要
刚体极限平衡法和有限元法在矿山边坡稳定性分析中经常使用,基于Slide和Plaxis两个计算软件,对矿山边坡整体稳定性分别进行模拟计算,得出Plaxis计算结果较Slide更为保守,二者差异不大,安全系数对弹性模量和泊松比的敏感性都较低,边坡形态对于两个软件计算结果差异影响较明显。
The rigid limit equilibrium method and finite element method are usually used to analyse the stability of mine slope. Based on the Slide and Plaxis calculation software,the overall stability of the mine slope is simulated and calculated separately. It concludes that the calculation results by Plaxis are more conservative than Slide,the difference between the two is little. The safety coefficient is less sensitive to the elastic modulus and Poisson＇s ratio,and the slope shape has obvious influence on the calculation results by the two softwares.
