This paper introduces the concept and characteristic of mass concrete,and then introduces the computing method about temperature of that,and this paper discusses the control method of the hydration heat. Based on the research of mass concrete bridge hydration heat control tech-nology,this can give a good example for other bridge construction.%分析总结了大体积混凝土的概念及其结构特点，列举出大体积混凝土一般的温度计算方法，并概括了大体积混凝土水化热的施工控制技术，经过对大体积水化热的控制技术研究可为大体积混凝土的施工提供技术参考。
