Roadbed settlement monitoring device and method based on distributed optical fiber sensing monitoring technology
The invention provides a roadbed settlement monitoring device and method based on a distributed optical fiber sensing monitoring technology. The device comprises a plurality of box-type box bodies, afixed round smooth steel pipe, a first movable round smooth steel pipe, a second movable round smooth steel pipe, a first optical fiber and a second optical fiber. In a roadbed filling process, the first optical fiber and the second optical fiber are connected through the box-type box bodies to form a complete line by setting a reasonable distance, the strain condition on the whole distributed optical fiber line can be monitored by utilizing the characteristics of distribution, high precision and the like of the optical fibers, and meanwhile, the settlement value of each box-type box body, namely the settlement value of a roadbed, can be calculated. The complexity of a point type monitoring method in roadbed settlement monitoring is avoided, manual repeated position movement is not needed,a roadbed monitoring network can be formed by designing a reasonable optical fiber route, roadbed settlement deformation conditions in a large range can be obtained by means of the monitoring network, and the roadbed monitoring efficiency is greatly improved.
本发明提供一种基于分布式光纤传感监测技术的路基沉降监测装置及方法，包括若干盒式箱体、固定圆滑钢管、第一可移动圆滑钢管、第二可移动圆滑钢管以及第一光纤、第二光纤，在路基填筑的过程中，设置合理的间距将第一光纤和第二光纤通过各个盒式箱体连接形成一条完整的线路，利用光纤的分布式、高精度等特点可监测整条分布式光纤线路上的应变情况，同时也可计算出各个盒式箱体的沉降值，即路基的沉降值。本发明避免了路基沉降监测中点式监测方法的复杂性，同时不需要人为的一次次移动位置，通过设计合理的光纤路线，可形成路基监测网，依靠监测网可得到大范围内的路基沉降变形情况，大大提高了路基监测效率。
