2the thickness of the water layer in the first annulus is 0.1m, when infiltrate experiment start time, because soil is in undersaturated condition, so the infiltration capacity of soil is strong, in unit interval, the infiltration capacity of water is larger, along with infiltrating the carrying out of testing, the saturation degree of soil increases gradually, and the infiltration capacity of the water in the unit interval reduces gradually, when infiltrate experiment proceed to 60 minutes time, the infiltration capacity of pedological unit time reaches 5.02E-08m
3/ s, is continued until the 90th minute, in the now unit interval, and the infiltration capacity of water is tending towards same numerical value, and namely soil infiltration amount reaches the steady state (SS) of infiltrating and testing, so get 5.02E-08m

Above-mentioned parameter is substituted into following formula by remote controllers, and can obtain vertical hydraulic conductivity K is 2.52E-07m/s, is converted into 00218m/d.
In formula: K is the vertical hydraulic conductivity of Rock And Soil, unit m/s; Q is the stable infiltration capacity of solution, unit m
3/ s; F is the area of the first annulus, unit m
2; Z is the liquid layer thickness of the first annulus, unit m; H '
kfor capillary pressure, unit m; The depth of penetration of solution when L is off-test, unit m.
