| 摘 要： | 本文基于对往返荷载下饱和砂土瞬态孔压变化机理和定量分析途径的已有研究成果,通过振动三轴试验,建立了计算往返荷载下饱和砂土瞬态孔隙水压力的具体数学模型。该模型考虑了导致瞬态孔压波动发展的主要因素,据初步的模型计算和试验测定结果的对比,表明该模型能够模拟瞬态孔隙水压力的实际变化过程.

| Abstract: | Based on the cyclic triaxial test results,a mathematical model for calcu- lating transient porewater pressure of saturated sand under cyclic loading is built in this paper.The main factors governing transient development process of porewater pressure are included in the model.It is verified by comparison with the observed change process of transient porewater pressure from the test that the model is of significance and usefulness. |
