摘要: 介绍三门健跳大桥钢管桁架拱采用主塔与扣塔合二为一的无支架吊装方法,针对该方法,提出相应的施工 控制计算方法。在该桥中,笔者首次提出了定长扣索法控制拱助轴线标高的方法,给出了节段控制标高和塔架偏 位计算公式。实践证明这种方法是可行的
关键词: 钢管拱肋, 安装, 控制计算
Abstract: This paper introduces non-bracket construction method, through which main tower and cable tower are united into one, setting arch segments in Zhejiang Sanmen Jiantiao bridge .Based on this method, the author put forward first the responsive construction control calculation method, then invariable cable method in controlling rib axiss level .It gives calculation equation for segmental control level and tower displacement .It is proved this method is practical .
Key words: steel tube arch rib , assemble , control calculation
