白杨河水库砼坝的地震动力分析

水坝抗震能力的评估在新疆具有重要的现实意义．采用有限单元法对白杨河砼坝的动力强度及稳定性进行了计算，结果表明地震时坝的破坏不取决于空库或是满库，而是与它们的周期有关；而且下游坝面遭到破坏的可能性大于上游坝面．在考虑水平及竖向地震荷载作用下，白杨河砼坝满足强度及稳定性要求。

SEISMIC DYNAMIC ANALYSIS ON REINFORCED CONCRETE DAM OF BAIYANGHE RESERVOIR

To assess antiseismic ability of reservoir dam is of important realistic significance in Xin jiang. The dynamic intensity and stability of Baiyanghe reinforced concrete dam are calculat ed with finite element method. The results show that the destruction of a dam isn't decided by which the reservoir is empty or full, but by the period of the dam. Moreover, the tail seg ment of the dam is easier to be destroyed than the upstream segment. Baiyanghe dam is up to the need of intensity and stability after considering horizontal and vertical seismic loading.
