Consideration is given to filtration under a Zhukovskii sheet pile through a ground layer underlain by a highly permeable head horizon the left semi-infinite part of whose roof is modeled by an impermeable base. A study is made of the case of flow where the velocity at the end of the sheet pile is equal to infinity and the flow rate takes on extremum values on both water-permeable portions of the boundary of the region of motion. Limiting cases of flow associated with the absence of upthrust and of an impermeable inclusion alike are noted, as is an adjacent scheme due to the absence of the two indicated extremum points. Solutions are given for two schemes of motion in a semi-inverse formulation, with the classical Zhukovskii problem being the limiting case of one scheme. Distinctive features of such models are noted. For investigation of these flows, use is made of a Polubarinova-Kochina method which allows exact analytical representations for motion elements. Results of numerical calculations and the analysis of the influence of all physical factors on filtration characteristics are given.
