摘要
斜靠钢箱下承式系杆拱桥是近几年发展起来的新型桥梁结构,该种桥型拱肋合龙段因其安装精确要求高、耦合作用复杂而成为施工的一大难点。以上海市康宁路蕴藻浜大桥主桥为实例,综合介绍该桥斜靠钢箱系杆拱71m大跨度合龙段的施工方法及保障措施,可供同类型桥梁施工借鉴。
Under Bowstring Arch Bridge is a new structure developed in recent years, which is kind of bridge closure arch rib segment due to the installation requires high precision, complex coupling construction to become a major difficulty.In this paper, the Shanghai Kangning road Yunzaobang bridge as an example, comprehensive introduce the bridge inclined steel box tied arch 71m long span closure segment construction methods and safeguard measures, for the same type bridge construction reference.
