Research on Construction Technology of Mass Concrete for Bridge Bearing Platform
-
摘要: 随着我国交通事业的高速发展,大跨度桥梁数量与日倍增,随之大体积混凝土承台也得到了广泛应用。研究发现,大体积混凝土在固化过程中将释放大量水化热,从而产生温度裂缝,影响结构的整体性。基于此,本文结合具体工程实例,对桥梁承台大体积混凝土施工工艺和温测情况进行了分析与探讨,以期为相关施工提供参考。Abstract: With the rapid development of my country's transportation industry, the number of large-span bridges has doubled daily, and mass concrete caps have also been widely used. Research has found that a large amount of heat of hydration will be released during the curing process of mass concrete, which will cause temperature cracks and affect the integrity of the structure. Based on this, this article combines specific engineeringexamples to analyze and discuss the construction technology and temperature measurement of the mass concrete of the bridge platform, in order to provide a reference for related construction.
