大体积混凝土严寒地区施工中的温度及裂缝控制措施

Temperature and Crack Control of Mass Concrete during Construction in Cold Region

随着管道建设的发展，在国内所覆盖的区域越来越大，严寒地区建设工程暴露出的问题也越来越多，其中大体积混凝土基础产生的裂缝问题尤其突出。通过实际工程的现场施工管理，从设计计算和施工的角度，分析了造成大体积混凝土裂缝的原因，并提出了如何预防和检查大体积混凝土裂缝的主要技术措施。

With the development of pipeline construction,the area of pipeline application in China was getting lager and lager;more construction problems induced also increased in cold regions,especially the issues of cracks in mass concrete.Based on the field management of actual construction,the reasons of cracks in mass concrete are analyzed according to the calculation and construction,and measures of how to prevent and inspect the cracks in mass concrete are proposed.
