摘　　要：依托于某大桥项目主墩承台混凝土工程,针对大体积混凝土温度控制的难题,结合工程需求及温控标准,从配合比优化、冷却水管布设、混凝土浇筑与养护等方面提出承台大体积混凝土温度控制措施,并对承台大体积混凝土进行现场温度监控。Based on the concrete engineering project of main piers of a bridge, in order to solve the problem of temperature control of mass concrete, combined with the engineering requirements and control standard, temperature control measures of mass concrete were put forward in several ways including the mixture ratio optimization, cooling water pipe layout, concrete pouring and curing. At the same time, on-site temperature monitoring of mass concrete has been carried out.
