摘要
结合白岩沟大桥的工程条件,介绍利用六四式铁路军用梁设计的大跨度无支撑拱架的结构构造及特点,并阐述了该拱架组拼、安装、预压、变形控制及横移的几个关键技术,可为类似工程的施工提供借鉴。
With the engineering conditions of the Baiyan＇gou Bridge as an example, the paper introduces the structural forms and characteristics of the support-free large-spanned arches designed by means of Type-64 military beams. It also expounds some of the key techniques for the assembling, fixing, pre-pressurizing, deformation control and transverse moving of the arch. It may serve as a reference for the construction of similar projects.
