【摘要】 通过冻土单轴蠕变试验结果分析,以西源模型为基础,假定冻土服从Mises屈服准则,推导出应用与数值计算的柔度矩阵;用三轴蠕变试验检验了冻土粘弹塑本构模型;获得了相应的试验拟合曲线。结果表明:蠕变理论模拟值与三轴实测蠕变结果相吻合,该模型可用于人工冻土工程设计。更多还原

【Abstract】 With the analysis on the single axial creep t est resul t of the freezing soil,base on the Xiyuan model and the assuming of the freezin g soil yielded to the Mises yield code,the paper derived the flexible matrix fo r the value calculation.The freezing soil viscoelastic plastic constructive equa tion was verified with trial axial creep test.A related test fitting curve was o btained from the test.The results showed that the simulated value of the creep t heory could be matched with the results of the trial creep measurements.The mode l can be applied to the design of the artificial freezing soil project.更多还原
