| 摘 要： | 依据已有的孔压增长模型和动三轴试验参数，采用有限单元法，对徐州市棠张镇铁路路基可液化场地进行了地震反应分析。按孔压比和最大往返剪切作用面上的动翦应力比较法划分了饱和粉土层的液化区域，并结合标准贯入试验判别结果、剪切波速判别结果以及Seed-Idriss简化法判别结果，对该场地粉土层的液化性能做出了综合评价。

| Abstract: | Based on the model of pore pressure increment of soil and the data of dynamic triaxial test of soil, the seismic response analysis of liquefaction ground is made for the roadbed of railroad in Tangzhang town, Xuzhou city, by using finite element method. The liquefaction districting of saturated silty soil layer is made according to the comparative analysis of pore pressure ratio of soil and dynamic shear stress on the largest shear surface with going back and forth. Combined with liquefaction differentiation results of standard penetration test, shear wave velocity test and Seed-Idriss simplification method, the comprehensive evaluation is made on the behaviour of earthquake-induced liquefaction of silty soil layer of the railroad roadbed. |
