心墙堆石坝坝体变形有限元分析

Finite-element analysis on deformation of core wall rock-fill dam

以某心墙堆石坝为实例,采用三维静力有限元法,详细模拟了工程地质条件和施工顺序,基于邓肯-张E-B模型,分析了不同蓄水方案的大坝坝体变形规律。

Taking a core wall rock-fill dam as example,using the three-dimensional static finite-element method,the engineering geological conditions and construction sequence of the dam were simulated in detail.The deformation rules of the dam body under different impoundment schemes were analyzed based on the Duncan-Chang E-B model.
