| 摘 要： | 对苏北地区典型的粉土进行试验研究,分析了饱和粉土的孔压发展规律和液化特性。探讨了不同因素对粉土液化特性的影响和变化规律,并对粉土和砂土的孔压变化规律进行了对比,得出粘粒含量越多粉土的液化势越高的结果;两者在施加循环应力后,孔压的的变化呈不同的发展趋势;同时提出了粉土孔压数值模型。

| Abstract: | This paper presents the test and research on typical silt conducted in Subei.It analysed the regularity of pore pressure and liquefaction behavior.The main purpose is to explore the liquefaction behavior affected by different factors.The liquefaction behavior of sand is discussed based on comparisons.The analysis resutts show that the higher the clay fraction,the greater of the liquefaction potential;and that the pore pressure will have different development trend under cyclic stress action.The authors proposed the model of pore pressure of the silt. |
