SYSTEM FOR MONITORING THE SUBSIDENCES OF A BALLAST OF A TRACK OVER A GREAT DISTANCE

摘要

System for monitoring possible subsidences of the ballast of a track, characterized in that it comprises: - transversal mechanical elements extending under the ballast and subjected to traction in the event of a subsidence in the tie of the ballast in the vicinity of said transversal elements, strain gauges which are fixed on said cables and which produce signals in reaction to the tension subjected by the transversal elements, and processing means to which said strain gauges are connected, said means processing their signals to detect the subsidences.
