大体积混凝土温度裂缝的产生原因及控制措施

The Cause of Temperature Cracks in Mass Concrete and Control Measure

大体积混凝土施工时产生的温度裂缝,破坏了结构的整体性、耐久性、防水性,影响结构安全和正常使用,危害严重。分析了裂缝产生原因,提出了在施工中应该采取的各种控制措施。

The temperature cracks produced in construction process of mass concrete, which destroy the robustness, structural durability, waterproofing performance of the architecture, result in many project problems. This paper analyses the cause resulted from the cracks of the shrinkage of the mass concrete and brings forward the construction methods of temperature control and anti - checking.
