| Popis: | Problem statement. The research materials outlined in this work make it possible to construct the design profile of dams from soil materials, taking into account the strong compressibility of the soil and check the strength of the foundation of soil dams in depth. In addition, the results obtained by us can be used to determine the lower boundary of the compressible thickness of the bases, to the upper boundary of which a distributed load of either a triangular or trapezoidal shape is applied. Methods. Theoretical studies of geomechanical processes using analytical and numerical mathematical methods. Analysis and generalization of the results of theoretical research. Results. In the course of writing this article, we obtained analytical dependences of stresses at the base of earth dams on the coordinates and applied to the upper boundary of the base of the trapezoidal external load and showed the methods of accounting. Scientific novelty. Analytical dependences of vertical normal at the base of a soil dam with a trapezoidal profile have been obtained. The profiles of the dam in the form of isosceles and non-isosceles trapezoids are considered. Practical significance. The research materials outlined in this work make it possible to construct the design profile of dams from soil materials, taking into account the strong compressibility of the soil and check the strength of the foundation of soil dams in depth. In addition, our results can be used to determine the lower boundary of the compressible strata of the bases, to the upper boundary of which a distributed load of either a triangular or trapezoidal shape is applied. |
