Great advances have been made in the research on the liquefaction distinguishing; and some methods have been matured. This paper is to probe into the differences among using different methods such as anti-earthquake design specification for architecture structure

anti-earthquake design specification for railway engineering

effective stress method of finite element for free field and effective stress method of finite element taking into account the change of stress status owing to subway tunnel’s construction. Finally

the mechanism for the differences is explained. So the paper is taken as a reference for the survey

design and construction of underground engineerings.
