摘　　要：以杭州绿地双塔工程为案例,介绍了一种创新性工艺——大跨度空间桁架式钢结构空中连廊施工技术。该工艺保证了大跨度钢拱快速、精准安装,同时不受施工场地限制,最大程度降低高空作业量,有效保证了安装工期,提高了施工的安全性、可靠性,可为今后类似钢拱连桥的安装施工提供一定的借鉴。Taking Hangzhou Greenland twin tower project as an example,this paper introduces an innovative processthe construction technology of long-span space truss steel structure aerial corridor.This technology ensures the rapid and accurate installation of long-span steel arch,while at the same time,it is not restricted by the construction site,reduces the amount of high-altitude work to the greatest extent,effectively ensures the installation period,improves the safety and reliability of construction,and provides a certain reference for the installation and construction of similar steel arch bridges in the future.
