Ship Load Response Test and Structural Bearing Capacity Assessment of High-Piled Wharfs

Abstract

Ship loads are most frequently exerted on wharf structures,which will inevitably cause different degrees of impact on the wharfs during berthing process of ships.In order to study the influence of the loads,this paper carries out field tests on the high-piled wharf in old ports of Lianyungang with different types of ship berthing loads,and re-checks and calculates the bearing capacity of the wharf according to relevant standards.It was found that structural response of the wharf to ship impacts is related with ship tonnage and berthing speed.In addition,the fender absorbing energy and ship collision force can be deduced according to fitting formulas.According to the results of field tests and re-checking calculation,the bearing capacity of pile foundation can meet the current functional requirements.
