港口工程沙土液化判别方法

沙土液化是场地和地基的地震效应的重要内容,我国港口主要采用基于标准贯入试验的沙土液化判别方法以及静力触探等原位测试方法,而欧美、非洲及东南亚大多采用Seed简化法以及基于概率与统计分析的估计方法。通过多种液化判别方法的分析,论证其合理性,针对不同性质的工程合理运用于水运港口工程抗震作用。

Liquefaction discrimination method for harbor engineering

The liquefaction of sandy layer is an important index of the site and foundation seismic effect.The liquefaction of sandy layer discrimination method based on the standard penetration test and static cone penetration test ,etc.are mainly adopted for the harbor engineering in China.However,the simplified method of seed and the estimation method based on the probability and statistical analysis are adopted in Europe and America,Africa and Southeast Asia.Analyzing a variety of liquefaction discrimination methods,we prove the rationality of the method.According to different kinds of project,we apply it to the seismic effect for the harbor engineering.
