摘 要: 为了研究淮南地区粉质黏土的剪切蠕变规律,采用单试样多级加载的加载方式进行了直接剪切蠕变试验,采用非线性回归的方式来处理试验数据,得出粉质黏土剪切蠕变的本构模型及其参数与剪切应力的对应关系,对比结果表明该模型能够较好地描述粉质黏土的剪切蠕变特性。 In order to study the shear creep law of silty clay in Huainan area, the direct shear creep experiment adopt the way of single sample multi-stage loading, use the method of nonlinear regression to process the experiment data, draw a silty clay shear creep constitutive model and the relationships between shear stress and parameters, the comparison results show that the model can well describe the shear creep properties.
