内容記述 The clarify the permeability of a soil crust, the constant head permeability tests were carried out on the kaolinite and the red soil, and the hydraulic gradient i where Darcy's law was valid and the saturated hydraulic conductivity of crusts mainly examined. For the kaolinite crust, the flux q gradually increased with the hydraulic gradient i, and reached its peak at different hydraulic gradients ranging from 80 to 100 and ended as a down-ward curve. For consolidated crusts at 70 hydraulic gradient of valid region of Darcy's a law, the q-i relationobtained by being tested at the hydraulic gradients below 70 was expressed as a straight line which had the saturated hydraulic conductivity of k=6.80 × 10^<-5>cm/s. For the red soil crust, all experimental data points of q and i were approximately on a straight line at the hydraulic gradients below 30, and thus k=2.50 × 10^<-4>cm/s was given.
