前言 1976年7月28日唐山地震波及天津,地表出现喷冒、隆起、凹陷、地裂等变形,地基失稳建筑物大量破坏。为了认真总结经验,搞好抗震工作,我院承担了“应用静力触探判别天津市区轻亚粘土地震液化的研究”专题。研究范围为天津市区8度地震区的轻亚粘土。研究的方法是,采用静力触探与钻探试验相结合进行轻亚粘土分层及取值的方法;以静力触探为主,结合土的物理力学性质,根据宏观调查结果,进行对比分析,以求得未来地震时预测轻亚粘土液化的判别方法。
Foreword On July 28, 1976, when the Tangshan earthquake struck Tianjin, surface deformations such as blowouts, uplifts, depressions, and land cracks occurred, and the foundations of the unstable buildings were destroyed. In order to conscientiously sum up experience and do a good job of seismic work, our institute undertook the “Research on the Application of Static Probing in Discriminating Seismic Liquefaction of Light Sub-clay in Tianjin Urban Area”. The research scope is light sub-clay in the Tianjin 8 degree earthquake area. The method of research is to use the method of static heel penetration and drilling to combine the methods of layering and value of light subclay; to use static cone penetration as the main method, and to combine the physical and mechanical properties of soil, according to the macro-survey results, to conduct comparative analysis. To determine the method for predicting the liquefaction of light sub-clay during future earthquakes.
