摘　　要：合龙施工是桥梁施工中的关键工序,对施工精度要求较高。论文依托实际工程,对塔梁固结形式的空间流线形提篮钢拱塔施工过程中主塔合龙段在自重和温度作用下的位移进行了分析,从而对拱形钢主塔合龙方案的设计提出指导性意见。Closing construction is the key process of bridge construction,which requires high construction precision.Based on the actual engineering,this paper analyzes the displacement of the closure section of main tower closure section under the action of weight and temperature during the construction of the steel arch tower with tower beam consolidation,so as to put forward guiding opinions on the design of the closure scheme of the arch steel main tower.

关 键 词：塔梁固结 空间流线形提篮拱 钢塔 合龙 位移分析
