岩体中裂隙愈多,裂隙的方向愈多样化,这种岩体就愈均质和各向同性。对多裂隙石灰岩的野外调查表明,当裂隙数量增加时,岩体的各向异性就减少。因此,在研究软岩边坡稳定性以及无序裂隙的硬岩边坡稳定性时可采用连续介质的弹性及弹-塑性平面问题求解的方法。如果岩体出现定向裂隙,那么可合理地应用有限元法来决定每一具体情况下岩体的应力-应变状态。采用有限元法可预先规定用离散模型来代替连续介质 The more fractures in the rock mass, the more diversified the directions of fractures, the more homogenous and isotropic the rock mass. Field investigation of multi-fractured limestone shows that as the number of fractures increases, the anisotropy of the rock mass decreases. Therefore, when studying the stability of soft rock slopes and the stability of hard rock slopes with disordered fractures, we can use the method of solving elastic and plastic-plastic problems of continuum. If oriented fractures occur in the rock mass, the finite element method can be reasonably applied to determine the stress-strain state of the rock mass in each specific case. The finite element method can be used to prescribe discrete models instead of continuous media
