铁路大跨长联连续梁桥的合龙顺序分析

Analysis on the sequence of concourse of long span continuous beam bridge of railway

以在建京沈客专潮白河特大桥跨潮白河河道(60+4×106+60) m连续梁为工程背景,通过建立不同合龙顺序下的有限元模型,对该桥合龙方案进行了优化分析,为该类桥梁合龙提供参考。

Based on the construction background of the Chaobai river(60+4×106+60)m continuous beam of the Chaobai river bridge in Beijing-Shenyang passenger dedicate,the closure scheme of the bridge is optimized and analyzed by establishing the finite element model under different closure sequence,which can provide reference for closure of this kind of bridge.
