| 摘 要： | 在考虑坝水耦合振动影响下，对拱坝边坡在地震作用下承受的动水压力进行了理论分析和数值计算。对正常蓄水位时、枯水位时边坡地震响应进行了分析。包括边坡的损伤演化、应力、位移的分析。在水坝地震动力分析中，应当将边坡、库水和地基三者作为一个综合的振动系统进行动力分析，考虑它们之间的相互作用，为类似库区边坡稳定性评价和边坡加固提供理论依据。 |
| 关 键 词： | 动力响应 蓄水位 枯水位 动力损伤 |

| Abstract: | Considering the effect of dam - water coupled vibration, this paper gives theoretical analysis and numerical calculation of hydrodynamic pressure of the arc dam slope under seismic action. Seismic response analysis of slope is given both under the normal storage water level and low water level, including the analysis of damage evolution, stress, displacement of the slope. In the seismic dynamic analysis of the dam, the slope, reservoir water and foundation should be considered as a comprehensive vibration system. Therefore, evidence can be provided for stability evaluation and reinforcement of the slop in similar reservoir area. |
| Keywords: | dynamic response storage water level low water level dynamic damage |
