摘　　要：湘府路项目万家丽立交采用D5200-240型塔式起重机进行钢箱梁架设,以满足一次性跨越既有万家丽高架桥的吊装需要。万家丽立交施工区域内受周边地理因素、邻近建筑物、交通压力、地铁交叉施工的影响,使得塔式起重机在位置选择、基础结构及安装方面困难较大。结合项目实际情况,综合考虑交通、地质、管线等条件的影响,采取合理的塔式起重机设计方案,并对塔式起重机的基础进行受力验算,确保了项目的顺利实施。D5200-240 tower crane is used to erect the steel box girder of Wanjiali Flyover of Xiangfu Road project, so as to meet the hoisting requirements of crossing the existing Wanjiali Viaduct at one time. The construction area of Wanjiali Interchange is affected by the surrounding geographical factors, adjacent buildings, traffic pressure, and subway cross construction, which makes the tower crane difficult in location selection, infrastructure and installation. Based on the actual situation of the project, considering the influence of traffic, geology, pipeline and other conditions, this paper adopts a reasonable design scheme, and checks the stress of the tower crane foundation to ensure the smooth implementation of the project.
