摘　　要：通过总结北京鲜活农产品流通中心工程应用缓粘结预应力空心密肋叠合楼板技术,探讨解决空心楼板施工过程中遇到的关键技术问题,包括空心楼板抗浮验算,空心楼板模架体系承重验算,由科学计算结果确定技术措施,解决楼盖大跨度结构缓粘结预应力施工,不同强度混凝土间完成一次性浇筑等关键问题,并总结了该工程空心楼盖各个工程施工要点,可为类似工程提供借鉴。In this paper, the application of prestressed hollow floor technology in the construction of Beijing Fresh Agricultural Products Circulation Center is summarized, and the key technical problems encountered in the construction of hollow floor are discussed. This paper focuses on two key problems of this technique, the first one is anti-floating technology of hollow slab, and second is the oneoff pouring of hollow slabs. Besides, this paper also summarized every main points of construction of hollow floor of this project, which can be used for reference to similar projects.

关 键 词：大跨缓粘结预应力钢混结构 空心楼盖 抗浮技术 整体浇筑
