Research on Moist soil infiltration law in coastal regions of Tianjin

摘要：

From 2005 to 2007 in Tianjin, soil infiltration tests were observed in Coastal moist soil regions. This paper used the least square method to analyze the soil infiltration law. Through the analysis that Horton solution has the clear physical meaning and it is more realistic. Infiltration parameters did not change significantly with the time. The mean value of stable infiltration rate is 1.629mm/min, and its coefficient of variation is 0.38. Stable infiltration rates value ranges from the range of 0.888-2.720 mm / min. The mean value of initial infiltration rate is 5.094mm/min, and its coefficient of variation is 0.54. Initial infiltration rates value ranges from the range of 1.944—10.994m m/min.
