冷却管在大体积混凝土浇筑中的作用研究

Function of cooling water tubes study on placing massive concrete

主要分析了浇筑大体积混凝土的过程中,使用布置冷却水管的方法以降低大体积混凝土的水化热、内外温差,改善应力的分布,从而控制裂缝产生,说明冷却管有预防大体积混凝土产生裂缝的作用,可保证桥梁质量。

A major content of the discourse is to discuss application of the method that using the cooling water tubes to describe the hydration heat and temperature difference between inside and outside of the massive concrete,thus can we improve the stress distribution in order to control the generation of the cracks and ensure the bridge quality.The result shows that the cooling water tubes are helpful in describing the cracks＇ generation of the massive concrete.
