摘要
挠度是评价桥梁结构安全性的重要指标。根据桥梁结构特点,选用半封闭连通管式差压传感器进行实际工程应用。论述了传感器的基本原理,介绍了实际的半封闭连通管式差压传感器及其系统的构成,并将该传感系统应用于荆岳长江公路大桥通车鉴定试验的静载挠度测量中,测量结果表明:半封闭连通管式差压传感器的测量数据能够有效地反映桥梁结构状态变化,且具有较高的测量效率和准确度。
Deflection is the important index for evaluation of bridge safety. According to structural characteristics of bridge, semi-closed connected pipe differential pressure sensor is adopted for deflection measurement. Basic principle of the sensor is dissertated, the composition of semi-closed connected pipe differential pressure sensor and the system is introduced, and the sensor is practically utilized in deflection monitoring of Jing-yue Yangtze River Highway Bridge. The result shows that measurement datas gained from semi-closed connected pipe differential pressure sensor can effectively reflect structure state change of bridge, and measuring efficiency, accuracy are enough high.
