| 摘 要： | 对露天煤矿均质边坡的渗流场及其对边坡稳定性的影响规律进行研究，根据温度场和渗流场的可比拟性，利用有限元分析软件ANSYS提供的岩土非线性弹塑性Druker-Prager模型及其前后处理程序，对边坡在渗流影响下的内部应力、位移和稳定性进行分析，采用强度折减有限元方法计算边坡的安全系数并得到边坡可能产生破坏的滑移面，这有助于滑坡治理方案的制定。

| Abstract: | This paper studies the seepage field of the homogeneous side slope in opencast coal mines and its influence on the stability of the side slope .According to the comparability of the seepage field and the temperature field ,it takes advantage of the geotechnical nonlinear elastic-plastic Druker-Prager model and the preprocessor and postprocessor procedures provided by the FEM software ANSYS and analyzes the internal stress ,displacement and stability of the side slope under the influence of the seepage flow .Using the strength reduction FEM method ,it calculates the stability coefficient of the side slope and identifies the sliding plane of the side slope that may cause damages ,w hich helps the making of sliding slope treatment plan . |
