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.
