合江长江一桥拱座大体积砼温度裂缝控制研究

Study on Hejiang Changjiang No.1 Abutment Temperature Cracking Control

大体积混凝土施工中的温度监控是预防裂缝产生的关键。文章以合江长江一桥拱座混凝土施工为例,介绍了优化混凝土的配合比、合理分层浇筑混凝土及采用水管冷却混凝土三种温度控制方法。

The temperature control for large volume concrete construction is the key for protecting cracks.The article take Hejiang Changjiang No. 1 Bridge as example to introduces three temperature control methods includes optimizing concrete mix ratio, separating the concrete pouring and using water pipe to cool down concrete.
