Abstract:Preventing seepage failure is one of the important targets in earth-rock dam’s seepage analysis .Due to the lack of the theoretical research for the seepage parameters of unsaturated soil ,the previous studies have focused on the saturated seepage analysis of earth-rock dam ,which could really reflect the dynamic situation of earth-rock dam’s seep-age .In this paper ,the unsaturated seepage parameters are primarily determined based on the characteristics of soil by us -ing soil character calculation software .The 1stopt data analysis and processing software are used for the data fitting and revision of the soil-water characteristic curve and unsaturated permeability coefficient curve combining with Fredlund mathematical model and VG mathematical model .The results show that the fitting correlation coefficient could fulfil the requirement of accuracy ,so it is reasonable and feasible using the corresponding fitting results to do the calculation of un -saturated soil seepage ,and the fitting result could be used for unsaturated soil seepage calculation .
