江汉湾桥两种钢拱安装方案的建安费对比

随着国民经济的发展，对于桥梁的形式，人们在安全实用的基础上，增加了对美的追求。近年来，拱桥因造型优美受到了人们的广泛青睐。然而，目前的市政定额体系对大跨度钢桁拱桥的费用测算实例较少，因此通过结合江汉湾桥实际情况，运用造价软件对大跨度钢桁拱桥的工法进行分析，对比架梁吊机施工和缆索吊机施工两种不同工法的建筑安装工程费用，分析两种工法在缆索吊、码头、栈桥、平台等方面的差异，为今后大跨度钢桁拱施工方案的选择提供参考。

Comparison of Construction and Installation Costs of Two Steel Arch Installation Schemes for Jianghanwan Bridge

With the development of the national economy, the people have increased the pursuit of beauty for the form of bridges on the basis of safety and practicality. In recent years, the arch bridge is widely favored by the people because of its beautiful design. However, at present, there are few examples of cost calculation of long-span steel truss arch bridges in the municipal rating system. Therefore, combined with the actual situation of Jianghanwan Bridge, the construction method of long-span steel trussed arch bridge is analyzed by using the cost software to compare the construction and installation costs of two different construction methods, i.e. the beam crane construction and the cable crane construction. The differences of two methods are analyzed in the cable hoisting, wharf, trestle and platform, which provides the reference for the selection of long-span steel truss arch construction schemes in the future.
