摘要： 作者导出了基于 Gibbs 自由能和应力内时标度基础上的海洋土内时剪胀方程,由此建立了预测均匀和不均匀波浪循环荷载下不排水时孔隙水压力的模型。该模型不仅很好地拟合了实验数据,还能较好地说明了循环荷载作用下孔隙水压力上升的机理,可以很方便地用于波浪循环荷载作用下的液化势分析中。

Abstract: An endochronic dilation model for marine soils on the basis of Gibbs free energy and stress intrinsic time scale is presented and used to found pore water pressure(pwp) equation to predict pwp under undrained uniform or non-uniform cyclic ocean-wave loadings. The equation is used for performing numerical simulation and prediction to some previous and writer’s cyclic test data. It is shown that equation provides a reasonable description for pwp under undrained cyclic loadings. The model is concise and its basic parameters are few and easy to decide. It is convenient to apply the model to the analysis of liquefaction potential under ocean-wave loading. The mechanism the progressive increase of pwp during undrained cyclic loading is also illustrated well by the model.
