摘要： 在工程建设中，液化判别对于优化工程设计与投资具有重要意义，结合某工程实例，比较了中国规范和欧美地区通行的简化Seed法对于同样场地的液化判别结果，结果显示，在细粒含量较高的粉性土液化地区，规范法的液化判别结果要明显高于简化Seed法。

Abstract: The liquefaction potential of a construction site has significant impact of the optimization design and the capital investment. This paper presents a state of the art review of the liquefaction evaluation of a site. The code method and simplified Seed method are used to evaluate the same site. The results indicate that a higher liquefaction potential evaluated by the code approach in higher fine content in silty soils, compared with the Simplified Seed method.
