【Abstract】 Tension infiltration meter is a kind of devices measuring soil moisture and solute movement parameters on the spot according to multi-dimensional infiltration theory. The measurement principle and methodology of tension infiltration meter are introduced,and the saturated conductivity of artificial-filled soil measured by the infiltration experiment in Panyuan is compared with that measured by soil infiltration meter. The result shows that the data obtained by multi-dimensional infiltration theory is very close to that measured by soil infiltration meter,thus the theory can be used in the measurement of soil hydraulic property parameters.更多还原
