公路分离式桥梁横向连接形式分析

Analysis of highway separable bridge cross connection form

指出桥梁一体化横向连接是公路桥梁拓宽工程中的新方法,不同的横向连接加宽方法对桥梁的性能影响不同,以分洪河大桥为例,针对刚接和铰接两种横向连接加固方法对桥梁结构性能的影响进行了分析,建议采用刚性连接方法,并提出了一种门形刚性连接方案,对类似桥梁横向加固具有参考意义。

It pointed out that bridge integration cross connection was new method of highway bridge widen engineering, different cross connection widen connection method had different influences on bridge property. With Fenhonghe Bridge as example, the rind connection and swing joint two cross connection reinforcement methods influences on bridge structural property were analyzed, the rigid connection method was suggested adopt, and a new rigid connection planning was proposed, which had reference meaning for similar bridge cross widen reinforcement.
