Damage analysis of deep water high pile cap foundations under different concrete corrosion by ship impact load

Abstract The deep-water high-pile cap foundation is in the water environment for a long time, which is likely to cause corrosion damage to the pile foundation concrete. At present, the damage analysis of the upper structure has received more attention and the technology is relatively complete, but the research on the damage identification and analysis of the substructure and foundation Relatively lacking. Due to the loading characteristics of the substructure, its own bearing characteristics and the geological watermark environment, which are quite different from the upper structure, the corresponding damage identification and damage analysis evaluation technology is quite different from that of the upper structure, so special research is needed.
