Study of slipping in the rubble-bedding of gravity quays

Horizontal slipping in the deep rubble-bedding of gravity quays was studied and a simplified method was put forward.The slipping was respectively analyzed by use of the method of original standand and the method considering the earth pressure on back of the rubble-bedding.The results of the two methods were compared with those of the elastic-plastic FEM called Plaxis.It was indicated that the result of the method considering the earth pressure on back of the rubble-bedding was coincident with that of Plaxis.There was a potential slipping plane in the rubble-bedding and its position was related to the height and width of the structure,load and parameters of the soil.
