Study on risk of ship collision in bridge life-cycle based on synergetic theory

Abstract

Studies on the risk of ship–bridge collisions have always been a significant subject in academic research. However, the study of ship–bridge collision risk is rarely mentioned from the perspective of the bridge life-cycle. This study proposes the concept of “bridge–ship common safety” based on the synergetic theory and constructed a high-level cooperative platform to solve the problem of bridge–ship collisions. This work analyzed the interaction between the subsystems of environment, ship and bridge. In this paper, a method for analyzing the ship–bridge collision risk is proposed based on synergetic theory with order parameters, including ship–bridge collision probability and the bridge's collapse probability. The Lanjiang Xiangnv Bridge project was taken as the background for this study. The bridge risk was evaluated by utilizing order parameters and synergetic degrees. The results show that the model can reflect the risk of ship–bridge collision, with a high level of scientific significance and academic value, enriching the bridge-collision prevention theory and implementing the concept of "bridge–ship common safety".
