广州解放大桥主桥拱肋整体吊装静力分析

近１０年来，我国钢管混凝土拱桥建设发展迅猛，已建成的跨度大于８０ｍ的约有４０多座，而无风撑下承式系杆拱桥仅２座，广州解放大桥是其中之一，并首次采用整体吊装施工方法．本文结合该大桥的施工实践，重点对单片钢管拱肋两点整体吊装的结构受力进行了静力计算及分析．

Static Analysis About Single Arch Rib in Hoisting of Jiefang Bridge in Guangzhou

The construction of Concrete Filled with Steel Tubular (CFST) arch bridge has been developed in the last ten years in our country. Although about 40 bridges whose spans are larger than 80 meters are constructed, there are only two through tied-arch bridges without wind bracing, including Jiefang Bridge in Guangzhou. It is well known that the integral hoisting construction method is firstly applied to this bridge. Then, the authors puts emphasis on the static calculation and analysis of two points integral hoisting construction method in single CFST arch rib in the paper associating with the construction practice of the bridge.
