摘要
分析了影响河道发生事故的概率和损坏桥梁概率的各种因素，给出概率的数学模型以判断桥梁在该河道上发生碰撞的可能性．其次，对影响船舶撞击力的因素：船舶撞击能量、标准船舶的选择、撞击力、撞击力作用点及撞击速度等进行了分析和讨论，给出了撞击力的计算方法．同时，对如何增强桥梁自身的防控能力和采取的防撞措施提出了具体建议．
The paper analyses all kinds of factors which influence the probabilities of accident happening in river course and of damaged bridge, give the mathematical model of probabilities in order to judge the collision probabilities of bridge in the river course. Then,it discusses the factors which Influence the strking force of shops:such as strking energy of ships, the choice of standard ships, the strking force and its acting point, and striking speed as well the calculating method of striking force is presented.At the same time, it puts forward practical adivces on how to heighten the ability to prevent the bridge itself from striking and the measures should taken to prevent striking.
