摘　　要：以上海国际旅游度假区的空间曲梁单边悬索桥为例,利用有限元软件进行分析,探索施工过程中主桥抬升方式对吊索安装的影响,并利用牵引索对抬升方案进行优化,确保吊索安装有一定的冗余量,减少安装过程中吊索受力,以保证后续施工的顺利进行。Taking the unilateral suspension bridge of space curved beam in Shanghai International Tourism Resort as an example,the finite element analysis is carried out for exploring the influence of the main bridge lifting method on the sling installation during the construction process.Meanwhile,the lifting scheme is optimized by using the traction cable,which can guarantee the redundancy of the sling installation and reduce the load on the sling during installation so as to ensure smooth follow-up construction.
