摘　　要：温度监测是大体积混凝土温控防裂的重要技术手段之一,然而大量的工程实践表明:现有监测手段仍然存在诸多不足,突出表现为温度测点可靠性与耐久性差、导线布设工作量繁重;温控参量需要人工读数并计算,无法实时捕捉混凝土内部温度信息。这给工程带来了安全隐患,无法满足现代化施工需要。为进一步完善大体积混凝土温度监测手段,开发一套包含无线温度传感器、传感器网络、智能监测软件为一体的大体积混凝土温度监测系统,并将其应用于某悬索桥承台大体积混凝土施工温控过程中。工程实践表明:该系统具有布设方便快捷、容纳温度测点数量大、智能化程度高等优点,实现了对混凝土温度信息的自动采集与存储、实时显示与预警、便捷管理与分析等应用需求,适合在工程中推广应用。Temperature monitoring is one of the important means for temperature control and anticrack the mass concrete construction process.However, there are still some drawbacks in the existing mass concrete temperature monitoring systems.For example there are large number of wires connecting to the temperature sensors, the monitoring parameters need to be calculated by hand. These drawbacks make the installation of temperature monitoring system very time-consuming and the information is not real-time.In this paper a mass concrete temperature monitoring system was developed, which was composed of wireless temperature sensors, wireless sensor networks and a smart monitoring software.The application of the monitoring system in the mass concrete construction of a large suspension bridge proved the convenience and reliability of the system.The features of automatic acquisition and storage of data, display and warning of the temperature of the mass concrete, data management and analysis made the system meet the requirements of the mass concrete temperature monitoring.
