摘要：
The swelling behaviour of kaolinite clay is systematically investigated by means of two types of oedometer device,; suitably modified to measure the variation of swelling pressure in dependence of the vertical and volumetric strain. A wide range of values for initial void ratio as well as initial and final degree of saturation has been covered. Based on the experimental results approximate equations for the swelling deformation are derived that are implemented in a FEM-Code. The application to a typical situation in practice is demonstrated by the numerical solution of the respective boundary value problem.
