摘要

利用Laplace变换取得了下卧与上覆层的组合地层在已知地震烈度或地层位移两种初始条件下的剪应力的解析表达式，提出了一种新的液化判别方法；并利用编程计算，分析了地层组合中各参数对砂土液化的影响，得到了在各种组合情况下砂土液化的难易程度。对工程判别有一定的理论指导作用。

Abstract

A new analytical solution which is about shearing stress of sand layer with underlying substratum and upper covering layer under the suppose of known earthquake intensity or layer displacement

is obtained by Laplace transformation; and a new differentiation method for sand liquefaction is proposed. Additionally

the influence of the soil parameters on sand liquefaction is analyzed by computer programming; from which the possibility of sand liquefaction can be judged under different combination conditions. It is of benefit to practical engineering judgement.
