摘　　要：为控制桩基承台大体积混凝土的开裂,确保其施工质量,需对施工过程进行有效的温度监测与控制。为此,从3个方面(浇筑体内、浇筑体外、监测频率)提出了桩基承台大体积混凝土的温度监测要点,从2个方面(入模温度、浇筑体温度上升幅度)提出了桩基承台大体积混凝土的温度控制要点,并结合某业务楼项目进行了应用介绍与分析,为相关工程开展大体积混凝土的温度监控提供了技术借鉴。In order to control the cracking of mass concrete of pile cap and ensure its construction quality,it is necessary to carry out effective temperature monitoring and control in the construction process.Therefore,the key points of temperature monitoring of mass concrete for pile foundation bearing platform are put forward from three aspects(pouring body,pouring body and monitoring frequency),and the key points of temperature control of mass concrete for pile foundation bearing platform are put forward from two aspects(molding temperature and pouring body temperature rise).The application is introduced and analyzed in combination with a business building project,It provides a technical reference for related projects to carry out temperature monitoring of mass concrete.
