摘要
本文在研究三峡地区地震地质环境和地震活动规律的基础上,结合模拟实验研究结果划分了三峡地区潜在震源区。确定出相应的地震活动性参数。并对三峡工程三斗坪坝址进行了地震危险性分析,给出了三斗坪坝址不同期限内的地震影响烈度和峰值地面加速度的超越概率。
On the basis of the study of seismic geological environment and seismic acti- vity regularities inth Three Gorge region and its neighbouring regions, the authors have classified the potential seismic hazard region of Three Gorge region and detected the parameters of seismic activity as well as analysed the seismic hazard of Sandoupin dam site for the Three Gorge project, according to the researching results of lasir holographic simulation test. Through making use of tie probability calculation method of seismic hazard analyses, transcendental probability of the seismic effect intensity and ground acceleration for Sandoupin dam site in different periods were obeained.
