摘要
结合工程实际,研究了夏季施工时基础开挖以及混凝土浇筑产生的水化热对基底冻土温度场的影响规律,可以为座落在冻土区的基础工程的设计与施工提供指导,并对相关工程采取必要的措施维护其稳定性及有关问题的进一步研究具有参考意义。
The effect on the temperature field of permafrost soil of base by excavation of a foundation and the hydration heat of cement in casting reinforced concrete was studied when construction in summer.The results may be a guidance to design and construction in related engineering practice,and it is expected to lay a foundation for further study on maintaining thermal stability of permafrost at the bottom of foundation.
