In this paper probability analysis method is introduced in the study on earthquake risk for the dam of the project. Comparison with conventional deterministic method has been conducted. Results of the analysis indicate that the probability method has marked advantages because it has considered various safety standards. According to calculation by fault fracture model, provided the transcendental probability is 0. 01 with consideration of design durability of major hydraulic structures being 100 years,design intensity of earthquake at Changzhou will be Ⅶ grade and maximum horrizontal acceleration a_(max)= 0. 12g. The author recommends this design intensity to replace the basic intensity other than raising its protection standard for higher intensity.

本文将概率分析方法引用于水电站大坝的地震危险性研究,并与常规的确定性方法进行了比较。分析结果表明,概率法考虑了不同的安全水平有明显的优越之处。根据断层破裂模型计算,如取超越概率为0.01,大型水工建筑物设计基准期按100年考虑,则长洲的地震设计烈度为Ⅶ度,最大水平加速度α_(max)=0.12g。建议以此“设计烈度”代替“基本烈度”,不再提高烈度设防。

Based on“The Seismic Risk Analysis of Jiayuguan City”,this paper anticipates the seismic disas-ter of Dacaotan earth dam. We calculate and analyse the dam’s nonlinear dynamic characteristics usingdynamic nonlinear finite element method,and give the possible pull-open regions on the dam' s surfaceand the possible plastic failure regions in the dam under l0%and 2%of exceedance probability duringaperiod of 50 years,andgive the acceleration time history and shear stress time history of several rep-resentative points....

A case study was performed on the Kezier Dam site. Based on the principles of maximum contribution and structure consistency, an effective peak acceleration (EPA)-based scenario earthquake method was put forward by combination of the virtues of the probability and determinacy seismic hazard analysis methods. The scenario earthquake parameters of the Kezier Dam site, including the magnitude, epicentral distance and response spectrum, for a transcendental probability of 2% for 100 years were given. The response spectrum of scenario earthquake obtained was compared with the response spectrum prescribed by seismic design codes and the probability-consistent response spectrum, and the rationality of the scenario earthquake method was verified.
