摘　　要：大体积混凝土施工技术复杂,影响因素繁多,施工质量难以控制,是影响工程质量的重要施工环节。以迪拜蓝天酒店项目为例,分析高温期大体积超厚筏基混凝土施工的重难点,对大体积混凝土施工质量控制措施进行阐述。结果表明:高温期大体积混凝土施工,应从原材料的选择、配合比设计、混凝土浇筑、养护、温度监测等方面考虑,制订合理的施工方案,减少混凝土裂缝的产生,提高施工质量。The construction technology of mass concrete is complex,there are many influencing factors,and the construction quality is difficult to control,which is an important construction link affecting the quality of the project.Taking the project of Ciel Tower as an example,this paper analyzes the key and difficult points of mass ultra-thick valve base concrete construction in high temperature period,and expounds the quality control measures of mass concrete construction.The results show that the construction of mass concrete in high temperature period should be considered from the selection of raw materials,mix ratio design,concrete pouring,maintenance,temperature monitoring and other aspects,so as to formulate a reasonable construction plan,reduce the occurrence of concrete cracks and improve the construction quality.
