摘　　要： 本文基于Finn等人提出的内时孔压模型,通过饱和砂土应变控制的振动扭剪试验,研究了孔隙水压力的增长规律,以有效剪应变轨迹长度参数为内时参量,提出了一个饱和砂土振动扭剪孔隙水压力的计算模型。通过对已有试验资料的检验表明,该孔压模型较Finn等人提出的内时孔压模型更具有广泛性。 Based on the endochronic pore water pressure model proposed by Finn etal the pore water pressure build up for saturated sand is studied through strain-controlled torsional cyclic apparatus, taking the length parameter of effective shear strain path as an endo chronic variable, a pore water pressure model for Saturated sand during cyclic torsional shear loading is proposed. Verification of the proposed pore water pressure model on the existing test results indicate the model proposed in this paper has better extensiveness than Finn's pore water pressure.
