摘要
由于已建跨河桥梁设计航道等级普遍偏低,船舶大型化发展日趋明显,虽然船舶大型化具有明显的规模经济效应,但是导致超航道等级船舶通过桥区水域安全风险增加。从船舶综合安全评估的角度出发,深入研究船撞桥的安全风险是十分必要的。本文基于AASHTO模型获得了船撞桥概率,分析了船舶结构损坏程度和倾覆力矩,评估了船舶翻沉和桥梁倒塌的风险灾害水平。
The large-scale development of ships is becoming increasingly obvious for pursuing the economic benefits, but it results in a fact that there is an increasing safety risk when large cargo ships pass the bridge area waters. From the point of view of vessels＇ integrated safety assessment, it＇s very necessary to make a deep study of the safety risk of ship collision with bridge. Based on the AASHTO model, the probability of ship collision with bridge is obtained, the damage degree and overturning moment of the ship structure are analyzed, and the risk disaster level of the ship＇s overturning and the collapse of the bridge is assessed.
