本文论述了在大体积混凝土施工中存在基岩变温对基础温差修正问题的前提是基岩中存在着裂隙;在一般情况下,基岩同步变温对于浇筑块的温度应力将造成不利影响。本文还对出现浇筑块基础贯穿性裂缝的原因提出了探讨性意见。
This paper discusses the prerequisite for the temperature difference correction of basement when there is bedrock temperature change in mass concrete construction, which is the existence of fissures in bedrock. In general, the synchronous temperature change of bedrock will adversely affect the temperature stress of the pouring block. This article also put forward some suggestions on the reasons of the penetrating cracks in pouring block foundation.
