In order to solve the problem that it is lack of reasonable and effective evaluation method and evaluation index in the detection and evaluation of high pile wharf,we study the structural evaluation index of high pile wharf combining with disturbing energy method.By using variationally principles and principle of minimum potential energy,we establish the index system of overall safety evaluation for high pile wharf structure based on its structural characteristics combining with disturbing energy method,and compare with the current code.The results show that the method can give the overall safety factor of the structure while evaluating the local components,which can reflect the contribution of different components to the overall safety.
