摘　　要：为研究大体积混凝土跳仓法施工技术,文中以某超大型公共建筑工程为例,对跳仓法施工在大体积混凝土中的应用进行分析,探讨其在控制温度裂缝和收缩裂缝方面的优势与效果,并提出了后浇带设计、混凝土浇筑养护和控温措施等关键技术要点。结果表明,使用跳仓法施工可进一步提高混凝土的抗拉性能和整体结构的耐久性,对推动地下空间开发和建设具有重要的理论和实际意义。In order to study the construction technology of bin hopping method for mass concrete,this paper takes a very large public building project as an example,analyzes the application of bin hopping method in mass concrete construction,discusses its advantages and effects in controlling temperature cracks and shrinking cracks,and puts forward the key technical points such as the design of post-pouring belt,concrete pouring maintenance and temperature control measures.The results show that the use of bin hopping method can further improve the tensile properties of concrete and the durability of the whole structure,which has important theoretical and practical significance for promoting the development and construction of underground space.
