| 摘 要： | 以岩土力学为基础的土坝设计方法,能够定性和半定量地分析坝体和地基稳定性、估算坝体和地基的沉降量,而不能全面分析地基和坝体内部应力应变状态.采用邓肯E-K模型,对水电站坝基和坝体在填筑和蓄水条件下的应力和变形进行了动态模拟计算,结果表明,坝体和心墙垂直和水平变形在竣工和蓄水期均符合规范要求,心墙在蓄水期间不会产生水力劈裂.

| Abstract: | The method of earth dam, which based upon rock and soil mechanics, can semi-quantitatively analyze the stability of dam and its foundation, and also calculate the settlement. But it cannot be used to analyze comprehensively the state of stress-strain. The author used E-K pattern of Duncan's model to computerize and simulate the stress and deformation of dam and its foundation under construction fillings and impounded water. The results show that vertical and lateral deformation of the dam and core wall are all satisfied with specified demands after construction and water impounded, and the hydraulic split failure will not occurred for the core wall during the period of water impounded. |
