[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.
