# 粘性土剪切变形中渗透性试验 研究及数学模型 Experimental Study and Mathematical Model on Permeability of Clayey Soil with Shear Deformation

A new seepage device was developed to measure permeability of clayey soil under different physical and mechanical status with shearing deformations. A series of seepage tests were carried out on a certain clayey soil and indicated that permeability of the soil was related with many factors, among which the shearing strain and confining pressure were the most important. Based on the testing results and mechanism analysis, a new relation model of permeability to reflect effect of physical and mechanical status was raised. The model was then fitted and checked by the testing results.
