地下空间工程大体积混凝土施工技术探析

Discussion on Mass Concrete Construction Technology for Underground Space Engineering

为提升大体积混凝土施工质量,文中基于中铁三局青岛上合示范区交大大道地下交通配套工程项目,分析了大体积混凝土施工特征,并从大体积混凝土的搅拌、运输、浇筑施工、振捣、泌水、养护、温度控制和冬季施工等方面,论述了大体积混凝土施工技术。

Mass、high-strength and concrete poured in hot season,due to the poor heat dissipation capacity of concrete,the heat generated by hydration accumulates inte filling efficiency of hydration products,improve the interface transition zone,and improve the deformation coordination ability of cement slurry and aggregate.
