摘要
本文结合拟建的下六甲面板堆石坝工程实例,对该坝进行三维非线性有限元分析,计算研究了坝体变形。在综合阐述堆石体的本构模型和面板堆石坝非线性有限元基本原理的基础上,运用数学、力学和坝工理论研究堆石的蠕变,得到坝体在不同时期的变形规律,预测了坝体长期的工作性态,从而得到一些有意义的结论。
The paper makes three-dimensional finite element analysis and calculates the deformation of dam body taking Xianliuxia rockfill dam with face slab as the example,studies the rockfill creepage with the mathematics,the mechamics and the dam theory on the basis of the principle for constitutive model of rockfill dam and non-linear finite element of rockfill dam with face slab,gets the dam deformation law in different time,forecasts the working state of dam in long-term and obtains useful conclusion.
