V.L.Polyakov On soil filtration deformations with initiation of accamulation zones |
Applied hydromechanics, Vol. 5 (77) ¹ 2, (2003) |
| An axissymmetric mathematical problem of unstructural particles redistribution within the domain of filtration deformations is formulated for two-fraction incoherent soil. A thorough analysis of the mobile particles accumulation nearby drainage (the accumulation zone) is carried out on the basis of the exact solution to the given problem. Proceeding from some empirical relationships (Kozeni-Carman and straitened deposition of particle association) a number of estimations are conducted of soil permeability (hydraulic conductivity) within the failure zone taking into account mobility of sediment fraction. |
