高层建筑基础底板大体积混凝土冬季施工技术研究与应用

Technology Research and Application of High-Rise Building Foundation Slab of Mass Concrete Construction in Winter

针对大体积混凝土冬季施工的特点,通过分析研究材料和温度对大体积混凝土冬季施工的影响,设计和优化冬季施工方案,并结合实际工程案例研究北方民用建筑大体积混凝土冬季施工技术。结果表明,通过施工方案的优化和精心的施工组织管理,可以避免大体积混凝土冬季施工过程中裂缝的产生,确保地下结构冬季的施工质量。

According to the characteristics of mass concrete winter construction, through analyzing the in-fluence of materials and temperature on the construction of mass concrete in winter, we design and optimize the winter construction scheme and study the technology of mass concrete construction in winter in northern civil construction combined with practical engineering case. The results show that through the optimization of construction scheme and elaborate construction organization and management, we can avoid the crack of mass concrete during winter construction process, to ensure the construction quality of underground structure in winter.
