摘　　要：本文总结了北京中科宏圣大厦地下室的底板及侧墙在施工过程中的一些经验,该工程通过采用补偿收缩混凝土技术,实现超长钢筋混凝土结构连续施工,不仅提高了结构的整体性,而且保证了工程质量,加快了施工进度,取得了良好的经济效益。This paper summed up some experiences in the constructing period of the motherboard and sidewall of the basement of Beijing Sino- Science Hongsheng Plaza. By using the technique of shrinkage- compensating concrete, the project realized continuous constructing in over- length RC structure, not only the integrality of the structure was im- proved, but also the quality was assured, the constructing schedule was shorted and good economic benefit was achieved as well.

关 键 词：补偿收缩混凝土 连续施工
