摘要
大体积混凝土施工是现代大型土木工程中的特种技术,工程技术人员必须从理论上认清制约大体积施工质量的基本原因。以工程实践为例分析了大体积混凝土温度应力形成机理,进行了大体积混凝土裂缝控制的施工详细计算,提出了切实可行的裂缝控制施工技术措施,对类似工程有一定借鉴作用。
Super-volume concrete construction technique is a special technique in civil engineering at present. Engineers must recognize the basic reasons that restrict the engineering quality of the super-volume concrete in theory. In this paper the causes of temperature stress are analyzed based on a project practice. The detailed calculations for crack control in super-volume concrete constructiou are carried out. At last, the measures to control cracks in large bulk concrete are expounded, which can be applied in other similar works.
