摘要
采用经验点椭圆模型进行地震危险性分析计算,关键是求条件概率P(Y>y/E_i,m),其难点是如何求取地震动衰减椭圆与凸多边形潜在震源的相交面积.本文将给出一种简便的通用性计算方法—"逐点计算法".
The key to the hazard analysis for earthquakes using experimental point-ellipse models lies in the solution of a conditional probability, P(Y≥y / E_i, m), in which the problem is referred to the determination of the intersecting area formed by the seismic moving attenuation ellipse and a potential source with a shape of protruding polygon. For this end, a method in common use for calculation point by point will be presented in the paper, which was proved to be uncomplicated.
