| 摘 要： | 以武汉地铁四号线二期工程中饱和砂为研究对象,通过室内动三轴试验,研究饱和砂在不同干密度、固结比及动剪应力比下的孔隙水压力发展规律。研究表明,武汉饱和砂的孔压增长可以用一个负指数模型进行描述,模型拟合结果与试验数据的一致性好,说明该模型具有一定的实用性。

| Abstract: | Dynamic triaxial test is applied to saturated sand of the second phase project of the Wuhan Metro 4th line.The test is purposed to study the developing behavior of pore pressure under different dry densities,consolidation ratio and dynamic shear stress ratios.The test results show that the pore water pressure increasing of Wuhan saturated sand can be described by a negative exponential function.The comparison of simulation results with test data show the practical applicability of the model. |
