摘要
新建连镇铁路大港特大桥(28+48+32)m连续梁跨越新捆山河。连续梁主墩位于河道中,且连续梁主墩的承台较小,支架结构体系如何设置是本桥0号块施工的一项重要内容,更是0号块施工的关键工序之一。本文主要介绍主墩承台结构较小时0号块支架结构体系设计、结构验算以及施工注意事项,可为同类桥梁结构提供有益的参考。
The newly built Lianzheng Railway Dagang Bridge(28+48+32)m continuous beam spans theXinkunshan river.The main pier of the continuous beam is located in the river channel,and the bearing platform of the main pier of the continuous beam is small.How to set the structure of the support structure is an important part of the construction of 0#block of the bridge,and it is one of the key processes in the construction of 0#block.This paper mainly introduces the design,structure check and construction precautions of 0#block support structure when the main pier cap structure is small,which can provide useful reference for similar bridge structures.
