| 摘 要： | 结合一试验拱坝数值方法研究了底缝对拱坝的非线性影响,坝体、坝基和接缝均考虑了材料的弹塑性,坝体,地基处理用Ｄｒｕｃｋｅｒ－Ｐｒａｇｅｒ准则模拟,接缝材料用Ｍｏｈｒ－Ｃｏｕｌｏｍｂ准则模拟,模拟了接缝的滑移、开裂等非线性行为,计算结果和试验值一致性较好。

| Abstract: | The nonlinear effect of
base joint on the performance of arch dams is studied with numerical method and model
experiment in this paper. Elasticity and plasticity of the dam,the foundation and the
joints are considered.The Drucker-Prager criterion is adopted for the dam and the
foundation,and the Mohr-Columb criterion is adopted for the joints.Good agreements between
calculated results and model experiment results are achieved. |
