某拱桥缆索吊装施工塔架设计分析

Analysis of the Cable-hoisting Construction Tower Structure Design for an Arch Bridge

以福建省寿宁县江瑶大桥的缆索吊装施工方案为工程背景,对初步设计的缆索吊装塔架结构进行了系统分析。经不同工况有限元受力分析和强度、刚度、稳定性计算与复核,在确保安全性前提下,从经济合理性角度提出了塔架结构优化设计建议。

With the engineering background of Jiangyao bridge cable-hoisting construction scheme in Shouning county, Fujian province, a systematic analysis of the preliminary design for the cable-hoisting construction tower structure was carried out. First of all, The tower＇s stresses in different working conditions were analyzed by the finite element method （FEM）, then strength, stiffness and stability of the structure were calculated and checked to ensure safety. Finally, some optimization design proposals for the structure were put forward from the angle of economical rationality.
