First,according to the results of tests in laboratory and evaluation of rock mechanical parameters, slope rock mass failure angles are calculated based on Mohr Coulomb criteria; Secon.
首先根据室内测试和岩体力学参数估算结果 ,运用摩尔-库仑破坏准则计算边坡岩体的破裂角 ;其次 ,运用弹塑性有限元数值模拟方法进行了变形破坏规律研
The improved Mohr-Coulomb failure theory is suggested to describe the failure surface.
非饱和土的抗剪强度包络面在几何学上是直纹面的一种,该包络面可用改进的摩尔-库仑破坏准则描述,并用试验验证了该公式的合理性。
