一种新型桥梁防撞装置的探讨

针对非通航孔桥墩结构单薄,抵抗船舶撞击能力小的现状,本文提出了一种桥墩前新型拦截消能装置.该装置在船撞力作用下,利用"跷跷板"原理,使水平铺置的拦截网旋转成竖立工作状态,能增加阻拦住失控船舶的机率,大大减少了拦截系统被船舶直接压过驶走的概率.后经计算和综合分析效果良好,其成果可为非通航孔防撞设计借鉴参考.

Study on A New Device of Anti-collision on Bridge Piers

For the current status that structural non- navigable spans of bridge piers are thin and do not have e- nough capacity of resistance of ship collision,the article reflects a new device of block energy dissipation in the front of piers. Under the action of ship collision force,the block net shifts its position from horizontal into erect with the principle of seesaw,increasing the probability of blocking ship and reducing the probability that the blocking system is directly drown out. Through calculating and comprehensive analysis,the device has good effect. The a- chievements can be taken as the reference for the design of anti- collision on non- navigable spans.
