| 摘 要： | 当前工程设计都是将边坡失稳破坏看成整体的剪切破坏即M-C剪切破坏,基本不考虑岩土体本身抗拉强度.而岩质边坡真实的破坏应该是张拉-剪切复合破坏,不应是传统不考虑抗拉强度的单一剪切破坏模式.利用FLAC3D软件,基于张拉-剪切复合破坏准则对岩体和结构面强度参数同时进行强度折减,与只考虑抗剪强度的情况进行比较来研究抗拉强度对...

| Abstract: | At present,it is always considered that unstable slopes are simply caused by shear failure(the failure of Mohr-Coulomb shear),but without the tensile strength of rock-soil mass.However,the true failure mode is composed of both tension and shear failure.Based on the composite failure criterion of tension and shear,FLAC3D software is used to analyze the strength reduction of tension and shear at the same time,and then the result is taken to research the effect on the rock slope stability by comparing with the... |
