摘要
结合宁波市庆丰桥主塔承台混凝土浇筑的施工实践,介绍了大体积混凝土施工期混凝土水化热温度及温度应力的估算思路和方法,叙述了施工期控制大体积混凝土水化热的主要措施。检测结果表明所采取的措施有效。
In connection with concreting the main pylon footing of Qingfeng Bridge in Ningbo, the thoughts and method are introduced to estimate the hydration heat and temperature stress arising from mass concreting, including the measures taken to control such heat during construction. The test shows such measures are effective.
