摘要
为确保混凝土坝施工初期和运行期的质量安全,设计了分布式温度监测系统。通过监测到的温度数据,详细分析了坝体的温度分布情况。测试结果表明传感器存活率达到90%以上,所采集数据可全面反映混凝土坝体的温度分布,验证了系统的有效性和可靠性。该温度监控系统可广泛应用于水电站大坝温度监测,为大坝安全性评估提供可靠的依据。
To ensure the quality safety of concrete dam during its initial period of construction and operation period, a distribu- ted temperature monitoring system is designed. Based on the measured data of the temperature, the temperature distribution of the dam body is analysed in detail. The test result shows that the survival rate of the sensors reaches over 90% and the data col- lected can reflect the temperature distribution of concrete dam body completely, while the effectiveness and reliability of the sys- tem are certified as well. This temperature monitoring system can be widely applied to the temperature monitoring of the dam for hydropower project and provide a reliable scientific basis for the safety assessment on dam.
