高速铁路桥施工要点探析——以跨绩黄高速铁路系杆拱桥施工为例

Construction Points of Tied-arch Bridge across High-speed Rail:Case Study of the Construction of Tied-arch Bridge across Jihuang High-speed Rail

系杆拱桥是一种外形美观、成本较低的梁拱组合体系桥,钢管混凝土组合材料在系杆拱桥中的应用能够解决材料高强化、施工轻型化问题,有助于提高拱桥材料的稳定性、耐久性、抗腐蚀性、抗压强度等性能,施工快捷方便,造价较低,且可以缩短工期,因而得到十分广泛的应用。本文以跨绩黄高速大桥1-96m下承钢管混凝土系杆拱桥为例对其施工要点进行分析,以此得出系杆拱桥的优越性。

Tied-arch bridge is the girder and arch combination bridge with beautiful appearance and low-cost. The application of steel concrete composite materials in the tied-arch bridge can solve the problems of highly fortified material and lightweight construction, can improve the stability, durability, corrosion resistance, compressive strength and other properties of bridge material, and its construction is convenient, cost is low, and duration is short, and it has a very wide range of applications. This paper analyzes the construction points of 1- 96m below bearing steel concrete tied-arch bridge across the Jihuang high-speed rail to obtain superiority of tied-arch bridge.
