土质斜心墙坝蓄水分析
首发时间:2008-09-17
摘要:本文结合土质斜心墙坝蓄水变形及实际运行中存在的问题,进行了有限元仿真计算。分析结果表明,蓄水后坝体的变形和应力分布都有明显的变化,其中最大沉降区域向心墙上游侧偏移,上游侧坝体围压显著降低。这与大坝变形规律吻合较好,因此研究成果具有一定的工程参考价值。

Analysis on declined-core earth dam with water storage
Abstract:Aiming at problems of deformation during reservoir impounding and in practical application ,declined-core earth dam is simulated by using the finite element method. Analyses show that the deformation and the stress have significant change after water storage,which indicated the maximum dam settlement area is toward upstream core wall , the confining pressures of upstream dam obviously decrease. the results of which are better to fit with dam’ Deformation Law. Therefore, the method applied in this paper is feasible and effective and the research results have considerable reference value in engineering.
Keywords: declined-core earth dam deformation of water storage simulation computation
