ABSTRACT: There are many methods available currently to measure the matric suction of unsaturated soil with various advantages and disadvantages such as cost, accuracy, reliability and the ranges of suction that can be measured. This paper describes ongoing development of a prototype matric suction sensor, which uses the principle of volume change by pore-water pressure of a porous material with a high air entry value. The limitations of the methods available, advantages of the prototype sensor compared to the other methods and the reliability/robustness of the sensor prototype are discussed.
RÉSUMÉ: À présent, il y a beaucoup de méthodes disponibles pour mésurer la succion matric des sols non satureés qui ont ses avantages et ses désavantages comme les prix, la précipprototype de capteur de la succion qui funccione sur le principe de changement du volume qui corresponde à un changement de la pression du pore du matériel poreau qui a une On discute méthodes disponibles.
