| 摘 要： | 对于建筑场地的液化判别方法已有很多的研究，而且形成一些较为成熟的方法。场地在修建隧道后的液化特性也会发生变化，而考虑这些变化进行液化判别的研究较少。作者旨在探讨《建筑抗震设计规范》、《铁路工程抗震设计规范》、自由场地的有效应力有限元法和考虑隧道修建后，应力状态改变的有效应力有限元法在场地地震液化判别之间的差异，分析了这种差异产生的原因，对地下工程的勘察、设计和施工有一定的参考价值。

| Abstract: | 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. |
