地震砂土液化机理及其判别方法研究综述

On earthquake sand liquefied mechanism and its judging methods

列举出由于砂土液化对工程建筑及人民生命财产所造成的不利影响,并探讨了地震力作用下饱和砂土的液化机理,对国内外判别液化的方法及液化机理和研究现状做了归纳和评述,为砂土液化研究和治理提供了必要的理论依据。

The study lists the sand liquefying unfavorable influence on the engineering buildings and people’s life and property safety,explores the saturated sand liquefied mechanism under the earthquake effect,sums up the methods for judging the liquefying at home and abroad,the liquefied mechanism and the research status,and provides the theoretic reference to the research and treatment of the sand liquefying.
