地铁车站大体积混凝土中心温度变化规律及控制措施

Mass Concrete Center Temperature Change Pattern and Control Measures in Metro Station

文章结合重庆地铁4号线衡重式挡墙大体积混凝土浇筑过程中混凝土中心温度变化规律,探讨了大体积混凝土中心温度计算方法,并得出了该挡墙每层浇筑厚度应控制在2.5 m以内的结论,最后结合工程实际,给出温度控制建议。

This paper discusses the methods of calculating the center temperature of mass concrete, focuses on the change patterns of central temperature of the concrete during pouring process of balanced load retaining wall of large volume concrete on Chongqing metro line 4. The wall layers should be controlled within 2.5m as described in the final conclusion. In view of the engineering practice, it makes some suggestions on the temperature control.
