Abstract: The clay layer substance is regarded as water-resisting layer in certain condition in engineering. Through the methods of model test, experimental research was carried out for determining methods of whether the clay layer is water-resisting layer and the distribution regularity of water pressure inside. Certain condition of clay layer for water-resisting layer is found out according to the experimental results; that is found out the relationship among the thickness of clay layer, permeability coefficient and water table height on the clay layer, initiative hydraulic slope is gained for certain clay layer, water pressure distribution regularity is also gained inside the clay layer which has been infiltrated water. Experimental results have some guidance effects for the practical engineering.

Key words: water-resisting layer, model test, water pressure distribution regularity, permeability coefficient, initial hydraulic slope
