| 摘 要： | 在评价边坡稳定性方面，采用弹性本构模型的有限元法是一种值得信赖的方法，它在诸多方法中能简便的处理复杂情况下岩土体边界和地质条件。本文介绍了有限元法边坡稳定性分析基本原理，并结合具体针对玉环高边坡区域构造特征和边坡的工程地质特征，应用有限元法建立了有限元模型及选取参数，进行了稳定性分析，得出了位移圉、应力图、安全系数图，定量的揭示和模拟边坡破坏、变形的过程和机制，并对边坡加固进行了可行的论证和建议。

| Abstract: | On evaluating the stability of slope, the FEM with the elasticity constitutive model is a reliable method, and it can deal with the boundary of rock -soil and geological situation simply under the complex condition. In this article introduced principle of FEM on stability analysis of slopeis, according to the region tectonic structure and engineering geological character, applying the FEM made the FEM model and defining the parameter of YuHuan high slope,then YuHuan high slope is analyzed by this method. Charts of displacement, stress and safety coefficient are achieved, the process and mechanism of rupture, deformation are simulated quantitatively. Also viable argumentation and suggestions for slope of reinforce are given. |
