Abstract
A system for detecting and pre-warning railway roadbed deformation includes: a control box and an optical fiber-pressure sensor group. The optical fiber-pressure sensor group is formed by disposing a plurality of optical fiber-pressure sensors into a cuboid shape, and is buried in the railway roadbed for detecting magnitude of roadbed deformation in each direction. The direction of the deformation can be acknowledged easily, allowing the staff to eliminate potential risks purposefully. A time series prediction algorithm is performed to forecast a trend of the roadbed deformation in each direction, such that the staff may purposefully overhaul and correct the tracks where the roadbed is deformed excessively. At the same time, the staff may overhaul the track before the magnitude of the roadbed deformation reaches a predetermined value. Potential safety hazards may be eliminated in advance, ensuring the safety for the operation of the railroad.
