Abstract: In order to reveal the influence of decreasing range of freezing air temperature (DRFT) on phreatic water flow, we set the depth of groundwater level of 87.5 cm through the freezing test device with two kinds of soil texture that are sandy loam and silty clay loam, three freezing schemes which are less DRFT, medium DRFT and larger DRFT were conducted and the phreatic water inflow was monitored. The results show that the phreatic inflow rate is larger if the soil freezing by larger DRFT and it is higher than that freezing by less DRFT about 51.8 mm and 50.7 mm for sandy loam and silty clay loam respectively on the 41th day. The larger of DRFT is, the more influence of soil texture on phreatic water inflow are, and the phreatic water inflow of sandy loam is higher than that of silty clay loam about 8.6 mm, 11.5 mm and 14.2 mm on the 41th day respectively for less DRFT, medium DRFT and larger DRFT. The smaller soil particles diameter is, the earlier of the phreatic water inflow respond to DRFT. The research results are significant for the scientific assessment of groundwater resources quantity and prevention of soil salinization at shallow groundwater areas.
