%X In order to study the stress and structural damage of high-piled wharf, we simulated three kinds of typical sections of a high-piled wharf  by using finite element method, and analyzed the pile bearing capacity. Then, we compared the simulated result with the damage detection result of pile foundation structure, and the results coincide  with each other, verifying  the correctness of theoretical analysis. Finally, we gave  the reinforcement measures for  the damaged parts. According to the finite element analysis of pile bearing capacity and measured results, we  concluded that pile top (1-2 m from beneath the pile cap) is the most vulnerable part. For the three typical types of cross sections, we should try to avoid using the forms of section one and section two. Because the horizontal bearing capacity of the two types of cross section is too small so that  the piles are likely to be damaged by horizontal force in the process of use. Besides, we put forward two   measures of reinforcing the damage locations of piles by enlarging  pile cap section and by steel hoop. But in concrete repair, under the premise of considering time factor and economic benefits,we should flexibly choose repair measures based on  summarizing  and comparing  the advantages and disadvantages of various measures to treat the damaged positions of the piles properly.
