大体积混凝土裂缝与施工问题研究

Research of Mass Concrete Crack and Construction Key Points

防止大体积混凝土裂缝问题是施工难点,裂缝产生的原因多且复杂,结合冬季施工的大体积混凝土设备基础,依据裂缝控制技术及施工方案,探讨了冬季施工混凝土裂缝的成因,结合工程实例分析了施工中存在的误区,给出了应对建议。提出裂缝处理的可行建议。

To prevent the problem of cracks in mass concrete construction difficulties, the causes of cracks and more complex,and combining with the winter construction of mass concrete equipment foundation, on the basis of crack control technology and the construction scheme, discusses the causes of cracks on concrete winter construction, combining with engineering examples, has analyzed the existing in the construction of myth, coping suggestions are given. A feasible suggestion for crack treatment is proposed.
