摘　　要：依据长春市某大型地下箱体工程冬期施工方法,对现场数据的采集、整理与研究,得出在气温–20℃以下施工时,采用广义综合蓄热法会使混凝土出现质量问题。通过逐一分析影响因素,提出解决对策,并在后期的冬期施工中得到验证,解决了在严寒天气,混凝土养护的难题,为类似工程提供参考。Based on the winter construction method of a large underground box project in Changchun City,and the collection,collation and research of the scene data,It is concluded that the generalized comprehensive thermos method will cause concrete quality problems when the temperature is below–20℃.The influencing factors are analyzed one by one,and the countermeasures are put forward,which are verified in the later winter construction.The problem of concrete curing in severe cold is solved,which provides a reference for similar projects.
