摘要
考虑地震动水压力作用和地基弹性的影响,采用《水工建筑物抗震设计规范》(DL5073-2000)推荐的振型分解反应谱法,对宝泉浆砌石重力坝进行三维有限元动力分析.计算结果表明,大坝整体上的应力和位移能满足抗震设计的要求.在坝踵局部区域、范围很小的拉应力不会影响大坝的安全.
Considering the seismic dynamic water pressure and foundation elasticity, the dynamic response of Baoquan masonry gravity dam is calculated by using the three-dimensional finite element method and the modesuperposition response spectrum method given in Specifications for Seismic Design of Hydraulic Structures ( DL5073 -2000). Calculation results show that the seismic requirements for the whole dam's stress and displacement can be met, and that the local tensile stress on the dam heel has little effect on dam's safety.
