Abstract
The present disclosure relates to a method for predicting soil hydraulic properties based on an upward infiltration experiment of a cutting ring soil sample. According to the new design approach, based on an inverse process of one-dimensional water upward infiltration analytical solution of homogeneous dry soils under a boundary condition of a constant pressure, by recording the data regarding cumulative infiltration amounts and infiltration times during the upward infiltration process of the cutting ring soil sample and a time for the wetting front to reach the upper surface of the cutting ring soil sample, a saturated hydraulic conductivity of the cutting ring soil sample is measured, and the soil hydraulic properties are quickly obtained. The present disclosure overcomes the defects that the methods in the prior art for measuring soil hydraulic properties are time consuming, low in efficiency, and not suitable for rapid acquisition of large area in the field, avoids the problems of multiple solutions and non-convergence of parameters, and improves the efficiency of acquiring soil hydraulic properties, thereby providing an effective means for the investigation of soil hydraulic properties in a large area in the field.
