边坡稳定分析数值法
numerical value method for slope stability analysis
b IonPo Wend一ng fenx一shuzh{fo边坡稳定分析数值法(n urnerieal value me‘hodfor slope stability analysis)确定边坡岩体某一区域内全部质点在开挖前后的应力和位移的分布状态，据此分析边坡岩体变形发展过程及其破坏形态、范围和边坡稳定性的应力分析方法。数值分析方法多用于几何形状复杂的边坡。 数值法中广为采用的方法有:(1)有限单元法。它是将边坡岩体离散化，在考虑开挖步骤与岩体不连续面等因素变换成为有限个单元的集合，相邻单元被具有共同位移的节点连接，采用标准结构分析的处理方式后，求解线性方程组，最后求出各节点的应力与位移值进行边坡稳定性的分析。(2)边界元法。此法具有降维作用，它是对已知边界条件的某域，把基本支配方程转换成相应的边界积分方程，然后通过对边界的离散化，建立相应的代数方程组进行求解。(3)为解决边界效应、节省计算费用的有限元与无限元相结合的方法。(4)吸收两种方法优点的有限元与边界元祸合方法。(5)以分离的块体为出发点，根据牛顿运动定律，结合不同的本构关系，用动态松弛法按时步进行迭代求解的离散元法。由于它允许块体有较大位移，甚至可脱离母体自由下落，故可直观地反映滑坡过程及其破坏形态。 由于计算机与软件开发的迅速进展，各种数值方法已逐步代替了模型试验方法，尤其是光弹模型法已很少采用。 (于润坤)
