摘　　要：北京鲜活农产品流通中心工程为框架剪力墙结构、钢结构、劲性混凝土结构。结构施工中,针对不同部位和施工难点,在超长大体积混凝土底板、大跨度超长结构预应力、劲性十字柱、梁柱核心区施工、混凝土空心楼板施工、结构消能减震,房心钢渣抗浮回填等方面采取了多项施工技术措施,保证了农产品流通中心工程的顺利施工,提高了结构工程施工技术水平,可为同类工程提供借鉴。Beijing Fresh Produce Distribution Center became frame shear wall structure, steel structure, strength of the concrete structure. In the construction of the structure, and different parts of the construction difficulties, the bulk concrete floor, a large span prestressed structure, stiff cross column core area beam construction, hollow concrete floor construction, the structure of energy dissipation, heart room aspects of anti-floating slag backfill construction has taken a number of technical measures. To ensure the smooth construction of agricultural products distribution center works to improve the technical level of structural engineering construction, provided the experience and methods can be utilized for similar projects.

关 键 词：超长大体积底板 劲性十字柱梁柱核心区 大跨度梁应力 空心楼板 消能减震
