摘　　要：大体积混凝土温度裂缝控制涉及多种因素,而对已浇混凝土的良好养护及精确测温则是关键所在。针对混凝土的养护与温测技术展开论述,详细阐述了蓄热保温法养护及温度与温度应力监测的实施过程,重点探讨与分析在此期间需要注意的多项要点。以某核电工程为实际背景,对大体积混凝土施工全过程进行实时温度监测,并充分强调养护与温测相互配合的重要性。Temperature crack control of mass concrete involves many factors, however, good maintenance and precise temperature measurement is the key. Maintenance and temperature measurement technology of concrete are described, and the implementation process of heat preservation thermal insulation maintenance method and temperature stress monitoring are indicated in detail. Matters need to be paid more attention are discussed and analyzed emphatically. In addition, taking a nuclear power plant project as practical background, real-time temperature monitoring in the whole process of mass concrete construction is carried out, and the importance of interaction between maintenance and temperature measurement is emphasized.
