利用标准贯入试验(SPT)结果判断场地在未来地震中是否会发生液化(液化势)是目前各国所采用的基本方法,本文在简单回顾了这一方法的发展历史的基础上,介绍了作者对于他1983年提出的液化势概率分析方法进一步发展情况。液化势随机分析方法的开发,为可靠性理论在基本建设抗震设计领域推广应用和修正我国现行抗震设计规范创造了条件。
The use of standard penetration test (SPT) results to determine whether the site will liquefy (liquefaction potential) in future earthquakes is a basic method used by various countries. This article briefly reviews the development history of this method and introduces the authors. For the further development of the liquefaction potential probabilistic analysis method proposed by him in 1983. The development of a stochastic analysis method for liquefaction potential has created conditions for the reliability theory to promote the use of seismic design in the field of basic construction and to modify the current seismic design code in China.
