| 摘 要： | 用三维非线性有限单元法对周公宅拱坝进行了基本荷载组合下的非线性分析和水压超载分析．结果表明：在基本荷载作用下坝体屈服范围不大，但右岸Fl和左岸F30处均有不同程度的屈服和开裂破坏，且这些地方有可能成为潜在的滑动面而影响坝肩稳定；超载系数在3．0～4．0之间．

| Abstract: | An analysis was made on the Zhougongzhai arch dam under basic load combination and overloading of hydraulic pressure by use of 3-D nonlinear finite element method. The results showed that the scope of dam yield was small under basic load combination, but different degrees of yields and cracking failures occurred at F1 on the right bank and F30 on the left bank, which might become latent sliding surfaces and decrease the stability of the dam abutment, and that the overloading coefficient of water density varied in a range of 3.0-4.0. |
