本文介绍了一种工程项目现场地震危险性评价方法。结果是地面运动参数（如峰值加速度）与平均返回周期的关系。该方法综合了所有潜在震源的影响和分配给它们的平均活动率。地点和潜在的点、线或面源之间的任意地理关系可以通过计算轻松地建模。在感兴趣的范围内，如果使用更普遍假设的震级分布和衰减规律，则导出的年最大地面运动分布为I型或II型极值分布。
This paper introduces a method for the evaluation of the seismic risk at the site of an engineering project. The results are in terms of a ground motion parameter (such as peak acceleration) versus average return period. The method incorporates the influence of all potential sources of earthquakes and the average activity rates assigned to them. Arbitrary geographical relationships between the site and potential point, line, or areal sources can be modeled with computational ease. In the range of interest, the derived distributions of maximum annual ground motions are in the form of Type I or Type II extreme value distributions, if the more commonly assumed magnitude distribution and attenuation laws are used.
