利用地震危险性概率分析方法对西部高震区某水电站工程所在场地进行地震危险性分析。根据区域地震活动性及地震构造研究成果，确定地震活动性参数，按照构造类比、历史地震重演原则划分了潜在震源区，应用概率方法计算出了场地不同概率水平的基岩水平向峰值加速度。其结果作为工程场地地震危险性分析结论，是抗震设计和决策的重要依据。

The method of probabilistic seismic hazard was used to analyze seismic risks of a hydropower plant site in high seismic areas of western China. According to findings of the regional seismicity and earthquake seismic structure, the study determined parameters of seismic activity, broken down potential seismic source in accordance with the structural analogy and the principles of historical earthquake recurrence, applied probability method to calculate the ground level of bedrock peak acceleration at different probability levels. Results of seismic risk analysis are important basis of seismic design and decisionmaking of the project site.
