桥墩在船舶撞击时的数值仿真和防护装置研究

Research on numerical simulation and protective device of pier in collision of ship

当船舶航行在河道中时,会存在一定的碰撞风险,尤其是与桥墩发生碰撞时,很可能会造成非常严重的财产损失,因此,在大桥设计之初必须采取必要的防碰撞措施,使得船舶在撞击桥墩时,能够最大限度降低事故的严重性。本文研究了桥墩在遭受到撞击时的受力模型,然后通过模型优化,对船舶和桥墩的受损情况进行了精确的分析,通过建立桥墩受损程度与船舶吨位和速度之间的关系,可以进一步对船舶的防护装置进行改进,从而大大增强了船舶和桥墩的安全性。

When a ship sails in a river, there is a certain risk of collision. In particular, when it collides with a bridge pier, it is likely to cause very serious property damage. Therefore, necessary anti-collision measures must be taken before the bridge is designed. This makes it possible to minimize the severity of the accident when the ship strikes the pier. In this paper, the force model of bridge pier under impact is studied, and then the damage of ships and bridge piers are analyzed accurately by model optimization. By establishing the relationship between the damage degree of bridge pier and the tonnage and speed of the ship, To further improve the ship's protective devices, thus greatly enhancing the safety of ships and piers.
