Abstract

Abstract

In order to study the failure mode and damage mechanism of a high-piled wharf subjected to underwater explosion, the experimental study on two models of the high-piled wharf under different explosive positions was conducted. The data collection and analysis for underwater loads and damage phenomenon of wharf models were recorded. The influence of explosive position on the damage effect and damage mechanism of high-piled wharf was analyzed. The results show the followings: The wharf is subjected to two times of loads under underwater explosive, which are the shock wave load composed of initial shock wave and underwater reflected wave, and bubble pulse load. The main damaged parts of the high-piled wharf are the middle and top of the piles, panel, longitudinal beams and the connection of the panel and beams. The explosive position directly affects the damage form of the wharf. Reducing the distance between the explosive and pile will increase the damage of the pile. When the explosive is located under the panel, the beams and panel of the high-piled wharf is seriously damaged.
