【摘要】 内河旅游观光船通常主尺度较小、重心较高、受风面积较大、稳性储备少、加之乘客数量多,如果发生船舶与桥梁相撞,容易产生翻船事故,酿成重大灾难性事件。为了提高船舶航行的安全性,降低船舶与桥梁碰撞发生灾难性事故的概率,在船舶设计阶段主尺度确定中引入风险评价论证方法是十分必要的。本文基于AASHTO模型,推导出定航线船舶营运期间碰撞桥梁的概率计算模型和灾害风险评价方法,并应用于清远北江客船船型的主尺度论证。更多还原

【Abstract】 Generally, river passenger ship has relatively small size, high center of gravity and large wind area, thus their stability margin is low. Meanwhile, the ships are often overloaded and easily overturn if they collide with a bridge. In order to increase the ships’ navigation safety and decrease the probability that disastrous accidents happen when the ships hit the bridge, it’s necessary to apply the risk assessment and demonstration method during the design of the ships’ principal dimensions. Based on model AASHTO, this paper deduces the probability calculation model and disaster risk assessment method of the ships’ hitting bridges during fixed-course vessel’s operation period and applies it to the demonstration of principal dimensions of the Qingyuan North River passenger ship.更多还原
