摘　　要：太湖水利试验厅钢屋盖采用大跨预应力空间桁架结构体系。为满足层叠的建筑造型和超大使用空间要求,结构形式独特,受力体系复杂,施工难度大,质量要求高。为保证施工安全和质量,对钢屋盖施工过程中的关键技术进行了研究,重点介绍了湿陷性场地加固技术、大跨度倾斜拱形桁架安装技术、防倾覆支撑体系应用技术、超长无撑杆拉索施工技术等。The steel roof system of Taihu Lake Hydraulic Laboratory adopts large-span prestressed space truss structure. In order to meet the requirements of stacked architectural modeling and super large tlse space, the structure is of unique form, complex loading, diffieuh eonstruetion and so on. To ensure the construction safety and quality, the key tee, hniques for steel roof construction are researched, ineluding the reinforcement technology of collapsible site, large-span inclined arch truss installation technology, anti overturning support system and super long cable without strut eonstruetion and so on.
