倾斜传感器在桥梁变形监测中的应用

Bridge Deformation Monitoring With Tiltmeter

倾斜传感器是一种测量倾斜角度的仪器。比较其它的测量方法,倾斜传感器以其安装方便、使用灵活、容易确立基准以及能适应恶劣环境下长期工作等优点和性能,在桥梁变形监测中被国外桥梁工程师广泛应用。详尽介绍了目前世界上主要生产厂家倾斜传感器的工作原理,如液体摆式、振弦式以及力平衡式。阐述利用倾斜传感器对桥梁的沉降、桥塔桥墩的位移以及梁体挠度等桥梁变形进行监测的原理,提出相应的简化模型和算法,并且列举各种变形监测的应用实例。

Tiltmeter is a kind of sensor for tilt measurement. Comparing to other technologies, tiltmeter has so great unique performance that it is proposed for bridge deformation testing or monitoring wildly abroad. We introduce some kinds of tiltmeters and the way how they work. In addition, some examples application to bridge deformation are presented.
