Asphalt pavement strain monitoring device based on optical fiber microbend loss and use method
The invention discloses an asphalt pavement strain monitoring device based on optical fiber microbend loss, which comprises a circular gasket 1, a compression cylinder 2 is arranged at the center of the lower end of the circular gasket 1, a part of the lower end of the compression cylinder 2 is inserted into a sleeve 3, the sleeve 3 sleeves the compression cylinder 2, a vertical column 4 is arranged in the compression cylinder 2, and a spring 5 sleeves the outer end of the vertical column 4. A tightly-wrapped single-mode optical fiber 6 is pasted on the outer surface of a spring wire of the spring 5, the bottom end of the sleeve 3 is fixedly connected with a base 7, and screws 8 are arranged at four hole positions of the base 7. Correspondingly, the invention further provides a using method of the asphalt pavement strain monitoring device based on the optical fiber microbend loss. The problem that roadbed pavement settlement change is difficult to monitor can be solved, and the device is simple in structure, high in precision and convenient to popularize.
本发明公开了一种基于光纤微弯损耗的沥青路面应变监测装置，包括：圆形垫片1，所述圆形垫片1的下端中心设置有压缩筒2，所述压缩筒2下端一部分插入在套筒3内，所述套筒3套在压缩筒2外部，内部设置有立柱4，所述立柱4外端套有弹簧5，所述弹簧5簧丝外表面粘贴有紧包单模光纤6，所述套筒3底端固定连接有底座7，所述底座7上四个孔位设置有螺钉8。相应地，本发明还提供了一种基于光纤微弯损耗的沥青路面应变监测装置使用方法。本发明能解决路基路面沉降变化难以监测到的问题，结构简单，精度高，便于推广。
