摘要
针对南京仙新路大桥主桥跨径大,主塔高及其N字钢结构及主索鞍安装难度大的问题,对北主塔塔顶门架进行了系统性设计,并对塔顶门架进行了数值模拟分析,结果表明,N字钢结构、主索鞍等构件安装质量满足要求。
In light of problems of Xianxin Road Bridge in Nanjing City,such as large-span diameter of the major bridge,high main tower,N-word steel structure and main cable saddle installation difficulty,the paper carries out systematic design and numerical simulation of the northern major tower roof gantry.Results show that:the installation quality of N-word steel structure and main cable saddle meets the requirements.
