| 摘要 |
The invention relates to an apparatus for physically analyzing soil or another natural, organized medium, comprising a sample changer (100) capable of receiving at least two soil-sample holders (1), said sample changer having a means for placing each sample holder and the sample (2) thereof in a measurement area, in turns, according to a cycle repeated over time, the apparatus including: a means for measuring the size of said samples; a means for measuring the potential of said samples containing water; and a means for measuring the weight of said samples, wherein all of said measuring means are grouped together in said measurement area so as to be simultaneously used implemented for a given sample when the latter is placed in said measurement area. The shrinkage curve and the water potential curve, which are obtained from said measurements, represent the change, over time, in the status of the water and structure of the soil sample during the drying thereof, and can be used to determine the hydrostructural characteristics of the soil. |
