Abstract
The purpose of the work was to determine the stress-strain state, to check the bearing capacity of structures (sheet pile walls, anchor rods) and the overall stability of soil prisms of the «structure-enclosing soil mass» system, taking into account its re-profi ling. According to the scope of work, computational study of the sheet pile wall structure of the excavation under the buttress foundation was performed (specifying the adequacy of the solutions adopted in the drawings for the length and spacing of the tie rods and the bottom marks of the sheet pile walls by section, as well as the struts in the west abutment and the need for geotechnical anchors. The computational studies were carried out with the PLAXIS software package. In the fi nite-element model there were realized: conditions of contact interaction of media; nonlinear and plastic properties of materials; geometrical nonlinearity in the form of staggered erection and sequence of loadings application.
