Beam-slab pile-supported wharf is an important wharf structural type in China.The wharf is inclined to be unusable in wartime by enemy strikes.For the rapid restoration of wharf functions,we analyze possible air and underwater explosions during war and terrorist attacks,and summarize damage modes of surface layer,longitudinal and transverse beams and pile based on research results from home and abroad.Then we analyze the damage characteristics of pile-supported wharf under air and underwater explosions,and propose suggestions for emergency repair methods for typical damage forms of various parts of wharf considering existing emergency repair methods and engineering application cases.The results show that surface layer,longitudinal and transverse beams and pile have different damage modes subjected to air and underwater explosion.The local damage includes cracks,spalling,craters,break,deformation.The overall damage includes the topside and pile foundation of the wharf have penetration failure.For different damaged parts and damage degrees of wharf,existing engineering technologies can basically repair the local damage in surface layer,longitudinal and transverse beams and pile.Prefabricated components can improve construction efficiency.Emergency repair for pile under water is of high technical requirements in design and more difficulty in construction.Pile repair is a key factor which restricts the construction speed and quality.Considering complex damage conditions and working during wartime,existing repair techniques still need be verified by practice.
