摘要
基于上海地区淤泥质饱和粘土的循环加载试验,总结了正常固结下淤泥质饱和粘土的孔压发展规律,在前人工作的基础上,引入等效超团结比的概念,描述了循环加载后饱和粘土的强度及模量的退化规律,从而确定了循环加载后其应力应变双曲线模型中的参数.
With the cyclic test results of saturated soft clay in Shanghai, the model to describe the pore presare development induced by cyclic loading in cyclic stress - controlled test is given. Based on the experimetal results andthe equivalent overconsolidation ratio hypothesis, the shear characteristics degradation relationships axe constructed forundisturbed NC soft clay and a method for predicting the stress - strain behavior after cyclic loding is proposed, whichcan be applied to calculating the settlement of soft clay induced by cyclic loading.
