倾角仪在桥梁安全监测中的应用研究
|
摘要
大型桥梁在新建和长期使用中对其性能的监测是非常重要的,其中挠度监测为判断桥梁健康状况的重要指标,对其检测的方法、原理和仪器也有多种,研究了采用倾角仪直接测量桥梁挠度的测试技术及其分析方法,具有算法先进、操作比较简单、仪器设备使用灵活、测量精度较高等优点。研究成果在实际工程取得了满意的效果,并已实现了推广应用。
In the new and long-term use, monitoring o f the large bridge performance is very important, and the deflection monitoring is an important index to judge the health condition of bridge, which has a variety of detection method, principle and instrument. This paper studies the test technology by using inclinometer direct bridge deflection and its analysis method, which has the advanced algorithm, simple operation, flexible use of equipment, high measurement accuracy,etc. Satisfactory results are obtained in practical engineering with its popularization and application.
