| 摘 要： | 本文在研究清江流域及外围区域地震地质条件和地震分布规律的基础上，划分了１、２个潜在震源区，并确定其相应的地震活动性参数，同时探讨区域地震烈度衰减规律及各潜在震源区对隔河岩和水布垭两坝址的影响烈度、进而复泊松模型，评价两坝址的地震危险性，获得了丙坝址不同期限内的地面峰值加速度及其相应的超越概率。根据对比分析，水布垭坝址的地震危险性比隔洒岩坝址小。

| Abstract: | On the basis of the study of seismic geological environment and seismic distributive regularity in Qingjiang river basin and its neighbouring regions. 12 potential seismic source regions and their parameters of seismic activity were determined. The reduction regularity of regional seismic intensity and seismic influence intensity of the potential seismic source regions on the two dam sites of Geheyan and Shuibuya were analysed. The seismic risk of the two dam sites were assessed by using Poission model, and ground acceleration and their transcendental probability for the two dam sites in different periods were obtained. According to the comparison analysis of seismic risk for the two dam sites, safety factor of Shuibuya dam site is larger than that of Geheyan dam site. |
