大体积混凝土结构施工中,由于水泥水化热引起混凝土浇注内部温度和温度应力剧烈变化,由此而产生的温度应力是导致混凝土产生裂缝的主要原因。本文以金水沟特大桥为例针对裂缝成因对大体积混凝土温度裂缝控制的施工措施进行了讨论及分析。
In the construction of large-volume concrete structures, the temperature stress and temperature stress caused by the cement hydration heat caused by the concrete pouring change drastically, and the resulting temperature stress is the main reason leading to the concrete cracks. This paper takes Jinshougou Bridge as an example to discuss and analyze the construction measures for controlling the temperature cracks of mass concrete based on the cause of cracks.
