This paper proposes the use of an algorithm based on the mercury intrusion porosimetry (MIP) method to obtain the water retention characteristic curve (pF curve) of a soil under different treatments. 3D X-ray micro-tomographic images were used to quantify pore size distribution, which was employed for the evaluation of the water retention in different matric potentials. The results showed very good agreement between the traditional method (obtained by suction tables) and that one based on the MIP algorithm. It means that the use of simulation procedures can be an interesting alternative for the measurement of soil water retention properties.

基于3D显微断层图像分析的土壤保水建模

本文提出了一种基于水银压入孔率法（MIP）的算法，以获取不同处理条件下土壤的保水特性曲线（pF曲线）。3D X射线显微断层图像用于量化孔径分布，该分布用于评估在不同基质势下的保水率。结果表明，传统方法（通过吸力表获得）与基于MIP算法的方法之间具有很好的一致性。这意味着使用模拟程序可能是测量土壤保水特性的有趣替代方法。
