The traditional static load test on the bearing capacity of piles in wharf needs to dismantle the upper structures,which costs large workload and long time.Based on the project of pile tests of an old wharf,we elaborate a fast and accurate method of pile static load test which maintains the integrity of the upper structure.The amount of loads was preliminarily determined through analyzing the load sharing ratio of pile by the finite element method.The sensors which can measure the loads on pile were installed on the pile top,and the bearing capacity of two piles were tested successfully by this method.
