Title (EN) APPARATUS AND METHOD FOR MONITORING LOSS OF SOIL COVER
(FR) APPAREIL ET PROCÉDÉ DE SURVEILLANCE DE PERTE DE SOL DE COUVERTURE
Abstract:
(EN) A device for determining a height of soil above a structure buried below a soil bed includes a sensor assembly comprising a total stress pressure sensor for transmitting a first signal indicating a total pressure, a pore water pressure sensor located proximate to the total stress pressure sensor, the pore water pressure sensor for transmitting a second signal indicating a fluid pressure, a sensor module configured to receive the first and the second signals, determine a difference between the first signal and the second signal, based on the difference between the first signal and the second signal, determine a height of soil above the sensor assembly, and transmit a third signal indicating the height of soil to an external device.
(FR) Cette invention concerne un dispositif conçu pour déterminer une hauteur de sol au-dessus d'une structure enterrée sous un lit de terre, comprenant un ensemble de capteurs comprenant un capteur de pression de contrainte totale pour transmettre un premier signal indiquant une pression totale, un capteur de pression d'eau interstitielle disposé à proximité du capteur de pression de contrainte totale, le capteur de pression d'eau interstitielle permettant de transmettre un deuxième signal indiquant une pression de fluide, un module de capteur configuré pour recevoir les premier et deuxième signaux, déterminer une différence entre le premier signal et le deuxième signal, sur la base de la différence entre le premier signal et le deuxième signal, déterminer une hauteur de sol au-dessus de l'ensemble capteur, et transmettre un troisième signal indiquant la hauteur du sol à un dispositif externe.
