[0002] In the process of road engineering construction and operation, the stability of roadbed is very important. Roadbed settlement is one of the common problems affecting road performance and safety. Traditional roadbed settlement monitoring methods have many defects. For example, the manual periodic measurement method not only consumes a lot of manpower and time cost, but also has low measurement frequency, and it is difficult to capture the real-time change of roadbed settlement. In some road sections with complex geological conditions or heavy traffic, roadbed settlement may change greatly in a short time, and manual measurement cannot timely discover these potential risks, which may cause road cracks, collapse and other diseases, and seriously affect the normal use of road and traffic safety. Therefore, some new roadbed settlement monitoring devices appear in the market.

When the top of the high slope settles, the protection cover settles with the roadbed, but the scale in the protection cover remains fixed, so the exposed size of the scale outside the protection cover will change. By measuring the change of the exposed value of the scale outside the protection cover each time, the roadbed settlement value can be calculated.
