| 摘 要： | 以西部地区某心墙堆石坝工程为例，在对大坝进行三维非线性静力分析的基础上，采用非线性动力有限元法对心墙堆石坝在地震作用下的响应做了数值分析研究，获得了坝体动应力、动位移、加速度等分布规律，并评价了土石坝的抗震安全性，为工程设计提供了参考依据。

| Abstract: | Taking core rockfill dam in West area for an example, based on three-dimensional nonlinear static analysis, nonlinear dynamic FEM is adopted to analyze the dynamic response of core rockfill dam under the condition of earthquake. The result reveals the law of dynamic stress, dynamic displacement and acceleration distribution of dam body; the aseismic safety of earth-rockfill dam is evaluated. Thus, it provides reference for design of practical engineering. |
