大体积砼冬期施工技术问题是控制裂缝的产生,大体积砼为实体最小尺寸等于或大于1m 的砼结构,或预计会因水泥水化热引起混凝土内外温差过大而导致裂缝产生的混凝土.在冬期施工中,内外温度差距很大,裂缝控制尤为关键、同时要注重早期受冻,在+5℃环境条件下浇筑,-10℃至+5℃环境条件下养护的1.8m厚筏板基础按照施工方案施工中总结形成的施工方法予以介绍.

large volume concrete winter construction techni-cal problem is to control the generation of cracks,mass conc-rete for entity minimum size is equal to or greater than 1 m of the concrete structure, or is expected to cause because of cement hydration heat of concrete temperature difference between inside and outside big cracks of concrete. In the winter construction, inside and outside temperature difference is big, so the crack control is key, noticing at the same time the early frost, and casting under+5℃environment conditi-ons ,-10℃to+5℃condition making maintenance of 1.8 m thick raft foundation construction scheme in accordance with the construction of the summary form construction method to be introduced.
