Description
Summary:The article considers non-pressure (gravity) filtration through a rectangular homogeneous cofferdam. Presented calculation method replaces the exact Boussinesq’s equation with integral relations. Position of the steady-state depression curve and seepage area are found based on a mathematical model, as well as numerical modeling using the Plaxis software package. Free surface of the filtration flow is calculated in short cofferdams (Λ = L / H = 0.5, 1) for the following two cases: with “dry” and “wet” downstream. The calculation results are compared with the data obtained by P. Ya. Polubarinova-Kochina using the conformal transformation method.
