摘要
在险峻陡峭的大山峡谷间架设钢管拱桥,钢管拱肋采用二次竖向转体施工方案,是桥梁施工安全架设的新方法。他具有结构合理、受力明确、降低风险、安全可靠的特点。此文根据澜沧江特大桥的结构和施工特点,探讨钢管拱二次竖向转体施工组织和施工工艺,并对二次竖向转体施工的工料机消耗和综合单价进行分析。
The steel tube arch bridge is usually built between the steep and steep mountain canyon, and the secondary vertical rotating construction scheme is adopted in the steel tube arch rib, which is a new method for construction of bridge construction safety. This construction scheme has the characteristics of reasonable structure, force definite, lower risk and safe and reliable. According to the structure and construction characteristics of Lantsang super major bridge, the construction organization and construction technology of secondary vertical rotating construction of railway steel tube arch bridge is analysis in this paper. And the consumption of artificial, material and mechanical and integrated unit price are analyzed.
