摘要
桥梁承台是典型的大体积混凝土,在施工中,若不采取相应的控制措施,则会因水化热过高、内外温差过大而产生裂缝。结合永定新河特大桥大体积混凝土施工实例,分别从温度控制、施工控制、测温方案等三个方面进行了分析和探讨。
Bridge cushion cap is typical mass concrete,the failure to taking appropriate control measures will produce cracks due to the too high hydration heat and great different temperature inside and outside.This paper unifies the example of the mass concrete construction to Yongding new river grand bridge,analyzes and discusses separately the temperature control,construction control and temperature measurement.
