大体积钢筋混凝土筏基施工

Mass reinforced concrete raft foundation construction

结合某大体积钢筋混凝土筏基施工实例,通过防裂的理论计算,提出了大体积混凝土施工裂缝控制要点,并从混凝土的配制和施工方法等方面阐述了其施工措施,实践证明该工程基础施工完毕后经观察未发现任何裂缝,满足使用要求。

Combined with the construction example of the mass reinforced concrete raft foundation, the author puts forward the crack control points in the mass concrete construction through the theoretical calculation of the crack prevention, describes the construction measure from the aspects of the concrete mixing and the construction method, the practice shows that the crack is not observed after the foundation construction of the project, and it meets the construction requirements.
