超高层建筑基础大体积混凝土施工技术

Construction Technology of Mass Concrete for Super High-rise Building Foundation

大体积混凝土技术作为超高层建筑工程中的一项关键技术,由于工程条件复杂、水泥水化热系数大,在实际施工中易出现混凝土结构温度变形、开裂等质量问题,影响超高层建筑基础结构安全与使用性能。因此,对超高层建筑基础大体积混凝土施工技术的工艺流程、操作要点进行阐述,提出技术质量控制措施,希望可以进一步提高工程施工水平,充分发挥大体积混凝土技术优势。

Mass concrete technology is a key technology in super high-rise buildings.Due to complex engineering conditions and large cement hydrothermal coefficient,quality problems such as temperature deformation and cracking of concrete structures are'prone to occur in actual construction,which affect the safety and performance of super high-rise building infrastructure.Therefore,this paper expounds the technological process and operating points of the mass concrete construction technology of super high-rise building foundation,and proposes quality control measures,hoping to further improve the engineering construction level and give full play to the technical advantages of mass concrete.
