摘　　要：沱江大桥主塔为空间扭转弧形钢斜塔,相比常规无倾角弧形钢塔,或有倾角但较矮的弧形钢塔,线形控制难度极大。为解决此技术壁垒,通过调研国内类似弧形钢塔项目,对线形控制进行专项设计和有限元分析计算。在此基础上,对2000t大型履带式起重机安装钢塔、门式提升架安装钢塔、3200t·m塔式起重机安装钢塔和竖转法安装钢塔方案进行比选分析及工艺研究。通过BIM碰撞,进一步加强对各方案的研究深度,详细模拟各方案在各施工阶段中,多种设备、结构的三维位置关系,数字化程度高。最后在工期、安全、技术可行、经济、设备资源等方面进行详细比选。The main tower of the Tuojiang Bridge is a spatial twisted arc-shaped steel inclined tower,compared with the conventional arc-shaped steel tower without inclination or the arc-shaped steel tower with inclination but shorter,the line shape control is extremely difficult.To solve this technical barrier,through the investigation of similar arc-shaped steel tower projects in China,special design and finite element analysis calculation for line shape control were carried out.On this basis,the installation schemes of the 2000t large crawler crane for the steel tower,the portal lifting frame for the steel tower,the 3200t·m tower crane for the steel tower,and the vertical rotation method for the steel tower were compared and analyzed,and the process research was conducted.Through BIM collision,the research depth of each scheme was further strengthened,and the three-dimensional position relationship of various equipment and structures in each construction stage of each scheme was simulated in detail,with a high degree of digitalization.Finally,detailed comparisons were made in terms of construction period,safety,technical feasibility,economy,and equipment resources.
