摘　　要：挠度是评价桥梁安全性的重要指标。根据桥梁各自的结构特点,选用连通管式光电液位传感器进行实际工程应用。介绍了该传感器的基本原理,阐述了实际的连通管式光电液位监测系统的构成,并将该系统实际应用于大佛寺长江大桥的状态监测中,监测结果表明:连通管式光电液位传感器的监测数据能够有效地反映桥梁结构状态变化,监测系统运行正常有效。Deflection is the key parameter for the evaluation of bridge safety. According to the structural characteristics of bridge, the connected pipe optoelectronic liquid level sensor is adopted for the deflection measurement. The basic principle of the sensor is introduced, the composition of connected pipe optoelectronic liquid level sensor monitoring system is discussed, and the sensor is practically utilized in the deflection monitoring of Dafoshi Yangtze River Bridge. The results show that the data gained from optoelectronic liquid level sensor monitoring system can effectively acquire the bridge deflection,and the system works effectively.
