Popis: 1. A method and program were developed for calculating nonlinear seepage in blastformed dams, which makes it possible to obtain the solution of the three-dimensional problem for an inhomogeneous, anisotropic region of a complex geometric form under arbitrary boundary conditions. 2. In a dam composed of material having a nonlinear law of seepage, the position of the surface of depression is higher than for the case when a linear (laminar) seepage law is used. 3. Consideration of three-dimensionality when solving the problem of nonlinear seepage in a blast-formed dam with a height of 70 m showed that the seepage discharge was somewhat greater and the position of the surface of depression was higher than for the case of the two-dimensional problem. This permits concluding the need for solving three-dimensional problems of seepage for structures of such a class. 4. Solution of problems in a three-dimensional formulation requires large expenditures of machine time. To increase the accuracy of the calculation, it is necessary to solve such problems on computers with a substantially higher speed.
