摘要
南水北调中线元氏1标混凝土建筑物,冬季施工中防止温度裂缝尤为重要,针对温控防裂采用了内部材料加热保温、外部环境保温升温等合理有效的温控措施,避免了裂缝的产生,为类似工程积累了经验,提供了借鉴。
It is par ticularly important to prevent temperature cracking in winter construction for the concrete buildings of bid 1 of Yuanshi section in the middle-line of the South-to-North Water Transfer Project. For this reason , we take steps to heat the internal material and keep external environment warming, the measures are reasonable and effective for tempera-ture controlling, and avoiding the generation of cracks. Through the engineer, we accumulated experience and provide a reference for similar projects.
