| 摘 要： | 利用“建筑”和“铁路”二种抗震设计规范，对南京地铁１＾＃线区间隧道地基进行了地震液化判别，发现两者有差异。详细分析了两规范对贯入点深度、粘粒含量、上覆非液化土层厚度、地下水闰等影响因素的不同考虑，认为不同的上覆非液化土层的考虑是导致差异的最大原因。

| Abstract: | Two anti earthquake design specifications for structure and railway are used respectively to judge the liquefaction of tunnel foundation of Nanjing Subway I in this paper. In two specifications, different considerations of factor influencing liquefaction, such as the depth of penetration point, content of clay, the thickness of unliquefied layer and the depth of underground water are analysed in detail. It is considered that different considerations of unliquefied layer result in difference in computations. |
