| Abstract: | It the condition of certain initial water content, research that the linear relation between loaded swelling ratio and semi-logarithm of vertical pressure, and dry density, and initial moisture. A simple constitutive model was deduced. It points out the model can be got by laboratory normal experiment and is a applied constitutive model which can reflect main property of soil in research area. |
