就那而言，在与传统的伪静电干扰方法和反应光谱方法分析水坝基础系统的滑动反的地震稳定性有一些限制，动态力量减小方法被用来响应强壮的导致地震的地面与一个复杂水坝基础学习一个高严肃水坝的深滑动反的稳定性行动。基于在平等者的岩石团的 shear 力量参数分配的减少承担的水坝基础的静态的滑动反的稳定性分析，地震时间历史分析被执行。为动态力量减小方法的建议不稳定性标准是动态排水量和塑料紧张精力的山峰价值随着力量减小因素的增加突然变化。水坝基础的 elasto 塑料的行为基于联系流动规则假设用 Drucker-Prager 收益标准被理想化。溢出水坝独块巨石的 elasto 塑料的时间历史分析的结果基于动态力量减小方法与动态线性有弹性的分析的相比，并且 elasto 塑料的时间历史分析的可靠性被证实。结果也证明分别地，在静态、动态的盒子中的水坝基础系统的安全因素是 3.25 和 3.0 并且 F2 差错在高严肃水坝的滑动反的稳定性上有重要影响。为动态力量减小方法的建议不稳定性标准是可行的，这也被结束。

英文摘要：

Considering that there are some limitations in analyzing the anti-sliding seismic stability of dam-foundation systems with the traditional pseudo-static method and response spectrum method, the dynamic strength reduction method was used to study the deep anti-sliding stability of a high gravity dam with a complex dam foundation in response to strong earthquake-induced ground action. Based on static anti-sliding stability analysis of the dam foundation undertaken by decreasing the shear strength parameters of the rock mass in equal proportion, the seismic time history analysis was carried out. The proposed instability criterion for the dynamic strength reduction method was that the peak values of dynamic displacements and plastic strain energy change suddenly with the increase of the strength reduction factor. The elasto-plastic behavior of the dam foundation was idealized using the Drucker-Prager yield criterion based on the associated flow rule assumption. The result of elasto-plastic time history analysis of an overflow dam monolith based on the dynamic strength reduction method was compared with that of the dynamic linear elastic analysis, and the reliability of elasto-plastic time history analysis was confirmed. The results also show that the safety factors of the dam-foundation system in the static and dynamic cases are 3.25 and 3.0, respectively, and that the F2 fault has a significant influence on the anti-sliding stability of the high gravity dam. It is also concluded that the proposed instability criterion for the dynamic strength reduction method is feasible.
