The oblique bearing pile nearby shore in a wharf was damaged at the joint of the oblique bearing pile and the pile cap. It is thought that under the horizontal component of the axial compressive force of the oblique bearing pile, the lack of jointing strength of the oblique bearing pile and the pile cap is the major reason for the damage. Besides, the soft ground, construction quality of the joint and overload of storage yard may also cause the damage. It is suggested to carry out the calculation for the connection of the oblique bearing pile and the pile cap or the transverse beam.
