Abstract:PHC pipe pile is widely used in water transportation projects of China,but the calculation method of shear bearing capacity is not clearly unified,so we carry out the shear test on three PHC800B110-5 pipe piles with diameter of 800 mm and wall thickness of 110 mm.Based on the observation of the crack development,deflection and failure state,we analyze the maximum principal stress,the maximum shear stress and the principal stress angle at the shear span;based on the study on the shear failure process of the test pile,we obtain the shear cracking resistance and shear ultimate resistance of the test piles.The test results show that PHC pipe piles still have load carrying capacity after cracking until they are destroyed.
