摘要
节理岩体边坡失稳破坏同时受控于节理与岩体抗剪强度。在对具有2组平行节理的岩体坡边失稳破坏机制研究基础上,研究了具有2组平行节理岩体边坡的极限平衡分析方法,并推导了相应的边坡稳定性分析计算公式,编制了基于潜在滑动面自动搜索的边坡稳定性研究程序。通过与文献中算例的对比研究,证明了所提出的节理岩体边坡稳定性分析方法的正确性,为具有2组平行节理岩体边坡的稳定性分析提供一条新的有效途径。
The stability of jointed rock slope is controlled by shear strength of joints and rock simultaneously. Based on the instability failure mechanism of jointed rock slope with two sets of parallel joints, a new limit equilibrium method is studied; and the corresponding formulae for stability analysis are deduced. A program is developed for the validation of this method. Through the comparison between the results obtained from the new method and those from reference , it is shown that the new method for stability analysis of jointed rock slope is correct; and it is also an effective approach for the stability analysis for jointed rock slope with two sets of parallel joints.
