摘要
将广义位移法应用于硗碛砾石土心墙堆石坝三维静力计算分析,用板、梁单元模拟防渗墙和廊道原结构的力学机制和几何特性,减少了模型自由度,提高了计算效率。同时将六面体单元与板、梁单元对比分析,两种计算结果基本吻合,防渗墙和廊道的位移和应力分布规律和数值均能满足要求。
Generalized freedom method is used to calculate three-dimensional static force analysis of Qiaoqi-earthcore rock-filled dam. It simulates the mechanics and geometrical characteristics of the prototype of cut-off wall and gallery using plate and beam elements, which reduces the number of the freedom of the model and enhances the computation efficiency. At the same time, hexahedron element is adopted to contrast analysis with plate and beam elements, the results of the two methods are basically consistent. The distribution of the displacements and stresses of cut-off wall and gallery and numerical results meet requirement.
