新建连盐铁路灌河特大桥防撞设施设计与分析

Design and Analysis on Anti-collision Equipment of Newly Constructed Guanhe River Extra-long Bridge in Lianyungang-Yancheng Railway

针对连盐铁路灌河特大桥设置防撞设施的必要性和防撞问题的特点,提出了两种防撞方案,通过非线性有限元碰撞计算对防撞设施进行分析,根据经济性、安全性的比选,最终确定了本桥的防撞方案,给今后桥梁防撞设施的设计提供了有效参考。

In view of the necessity for anti-collision facilities and the features of anti-collision problems of the Guanhe River Extra-long Bridge in Lianyunganng-Yancheng Railway, the paper proposed two anti-collision schemes. Through analyzing the anti-collision facilities by collision calculation with nonlinear finite element methods, the anti-collision program was finalized based on the comparison of economy and security. It could be served as a reference for design of bridge anti-collision facilities in the future.
