| 摘 要： | 本文从准平面问题的基本原理出发,用非线性弹簧单元模拟侧面阻滑力作用,建立了一种可以考虑岩体侧面阻滑力影响的重力坝深层抗滑稳定分析的非线性有限元实用计算方法,并编制了相应的ZMF-2电算程序。通过模型试验验证和算例说明此种方法是可行的。

| Abstract: | A nonlinear finite element method is presented for stability analysis of gravity dam against deep sliding in consideration of the effect of lateral shearing resistance of rock mass. The method is based on the principle of quasi-planar problems and simulates the effect of lateral shearing resistance of rock mass by using nonlinear spring elements. The computer program ZMF-2 was complied accordingly and examined by a model test and an example. It is shown that the method is feasible. |
