| 摘 要： | 采用三维弹塑性有限元方法，模拟施工程序和加载过程，考虑坝体基础相互作用，利用强度储备系数法、超载系数法和能量法等，对坝体－坝基系统进行渐进破坏过程计算分析。计算结果表明，模拟破坏的方法不同，其渐进破坏过程和失稳模式不同，相应强度储备安全系数和超载安全系数也不同，而用强度分析法和稳定分析法求得的极限承载能力完全一致，大坝的稳定安全度满足要求。

| Abstract: | This paper adopts three dimensional elasto-plastic FEM and simulates truly construction and reservoir impoundment process, considering interaction between dam and base. The authors apply strength accumulation coefficient method, over loading coefficient method and emerge method on calculation analysis about gradual destruction process of arch dam and base system. The computation result shows that different simulation methods lead to different gradual destruction process and different unstabilization model, and corresponding strength accumulation coefficient and over loading coefficient are different. Limit loading capacity of arch dam is completely consistent by Strength analysis method and stabilization analysis method. The stabilization safety meets demand of design. |
