| 摘 要： | 对取自徐州市棠张镇拟建京沪高速铁路路基的粉土,在试验室内按不同的干密度和细粒含量进行重塑,完成了三组不同干密度和四组不同细粒含量的振动三轴液化试验。分析了粉土干密度和细粒含量对饱和粉土抗液化强度的影响;通过曲线拟合方法建议了粉土振动液化过程中的孔压增长模型和永久应变势模型,给出了模型参数。 |
| 关 键 词： | 粉土 液化 三轴试验 孔压模型 永久应变势 |

| Abstract: | The silt samples studied in this test program were reconstituted in term of four different fines content and three different dry densities.The silt is from the roadbed of railroad in Tangzhang town,Xuzhou city. Seven sets of tests were carried out with dynamic triaxial apparatus.The liquefaction resistance affected by fines content and dry density of silt was analyzed.The dynamic models of development of pore water pressure and residual strain of silt are suggested by fitting a curve to the test results,and the parameters of these models are provided. |
| Keywords: | silt liquefaction dynamic triaxial test pore water pressure model residual strain power |
