摘要
对文献[1]提出的用点源模型确定假想地震的方法作了进一步的改进和补充,给出了用断层破裂模型确定假想地震的方法.并首次尝试运用概率一致的假想地震进行砂土液化的评估,为进行以概率为基础的砂土液化小区划找到了一条捷径.
The technique proposed by reference [ 1 ] for the determination of scenario earthquake based on point source is improved and supplemented in this paper. A method of determining pro bability--c o us is ie nt s c ena ri o e arthqu ake on the basis of Possion process and Fault--Rupture model is developed. And we have tried to apply the probability--consistent scenario earthquake to the prediction of saturated sand soil for the first time. Thus a shortcut for the microzonation of liquefaction based on probability is discovered.
