跨营业线门式框架桥可移动式支架设计应用

Design and Application of Portal Frame Bridge with Movable Support Across Existing Railway

依托某市政跨铁道路工程,详细介绍了一种采用可移动支架浇筑框架桥的新型施工方法,并采用Midas-Civil软件对支架结构进行了计算,总结了新型支架的施工过程及注意事项.研究表明支架结构受力满足规范要求,最小安全系数为1.5,施工时应严格按照设计要求搭设支架,做好对既有铁路的安全防护.

This article relies on a municipal cross-road railway project and introduces in detail a new construction method for pouring frame bridges with movable supports.The bracket structure is calculated by using Midas-Civil software,and the construction process and precautions of the new supports are summarized.The research shows that the strength of the support structure meets the requirements of the code,and the minimum safety factor is 1.5.During construction,the support should be erected in strict accordance with the design requirements,and the safety protection measures for the existing railway should be well done.
