Abstract:
The invention discloses method for determining hydraulic parameters and water inflow in the erosion stage of gravel soil, comprising: calculate the soil particle content P and the soil porosity n of each grade of particle size a, and draw the PSD curve of each grade of particle size and the soil particle content P of each grade of particle size and the PSD curve cluster of each grade of particle size and the soil particle content P of each grade of particle size in each erosion stage; calculate the equivalent diameter Dh of the soil particle, and calculate the minimum equivalent pore diameter d0 of the soil particle; calculate the critical hydraulic gradient icr of particle erosion at each stage; calculate the permeability coefficient kh; calculate the seepage flow velocity ν and the total seepage flow Q.
