| 摘 要： | 阐述了饱和砂土的动有效抗剪强度，往返荷载下的物态变化规律，以及基于物态变化、剪切变形非线性、剪缩剪胀性和压缩回胀性的有效应力应变本构特性。揭示了动载下饱和砂土存在塑性阻尼和粘滞阻尼。提出了广义Ｂｉｏｔ固结理论基础上考虑真实粘滞阻尼特性的饱和砂土反应分析新途径。

| Abstract: | This paper deals with the dynamics strength, physical state variations and constitutive relation, including the property of nonlinear shear contraction and dilatation, pressing contraction and elastic volume back of saturated sands, Based on the generalized Biot consolidation theory and effective stress constitutive, this paper also suggests a new analytial approach of saturated sand reaction in considering the real viscous damping behaviours. |
