摘　　要：望京SOHO-T3工程地下建筑面积38212 m^2,底板厚1200~3200mm,最厚达8850mm。施工中从大体积混凝土的特点入手,结合现场实际情况,编制了切实可行的技术方案,保证了混凝土连续浇筑;采取措施降低混凝土内外温差,加强养护工作,确保了大体积混凝土质量。In Wangjing SOHO-T3 project, the underground structure covers 38 212 m2 of building area and the bottom plate is 1 200-3 200 mm thick, with the characteristics of massive concrete are considered and technical scheme to guarantee successive concrete between inside and outside temperatures of concrete, maximum thickness being 8 850 mm,During construction, practical field conditions are analyzed to compile feasible pouring; measures are adopted to reduce the difference to strengthen the curing work and to guarantee massive concrete quality.

关 键 词：基础底板 大体积混凝土 混凝土防裂
