【摘要】：为提高内河观光船航行安全性,降低撞桥灾难性事故发生的风险水平,基于AASHTO模型进行船撞桥概率预报,分析撞击力对船首结构安全和船舶大倾角稳性的影响,提出船撞桥风险评估方法.应用该方法对某内河观光船撞桥风险进行评估,并讨论船速和桥墩防撞装置变形系数对船首结构安全和船舶大倾角稳性的影响.结果表明:船舶通过桥区水域时,若适当降低航速,可避免由撞桥导致的船舶倾覆事故的发生;增设弹性或柔性防撞装置,增加防撞装置变形系数,可减少船舶结构损坏程度,避免船舶倾覆.评估方法合理,结论可供内河观光船安全航行参考.
[Abstract]:In order to improve the navigation safety of inland river sightseeing ships and reduce the risk level of catastrophic accidents caused by bridge collision, the probability prediction of ship collision bridge based on AASHTO model is carried out, and the influence of collision force on the safety of bow structure and the stability of ship with large dip angle is analyzed. The risk assessment method of ship collision bridge is put forward, which is used to evaluate the risk of collision of a inland river sightseeing ship. The effects of ship speed and deformation coefficient of pier anti-collision device on the safety of the bow structure and the stability of the ship with large dip angle are discussed. The results show that if the ship passes through the waters of the bridge area, the accident of overturning caused by the collision can be avoided if the ship's speed is reduced properly. Adding elastic or flexible anti-collision device and increasing the deformation coefficient of anti-collision device can reduce the damage degree of ship structure and avoid ship overturning. The evaluation method is reasonable and the conclusion can be used as reference for the safe navigation of inland river sightseeing ship.
