摘要
利用全自动多功能三轴仪进行了砂土液化后大变形试验 ,基于试验结果提出了一个描述砂土液化后应力应变关系的双曲线模型 ,并对模型参数进行了标定 ,通过与前人试验结果比较验证了模型的适用性。结果表明双曲线模型可以较好地反映砂土液化后的应力应变关系
The laboratory tests on the post liquefaction deformation of sand are performed by a new vibration torsional triaxial apparatus, and a constitutive model on the post liquefaction behavior of sand is established with a hyperbolic model. The parameters of model are calibrated. It is found that the hyperbolic model can express the post liquefaction stress strain response very well by comparison to the previously published test results.
