Popis: | Characteristic features of the assignment of boundary conditions for the design of shallow structures are addressed. A computational procedure based on the finite-element method (FEM) is developed on the basis of a scheme with “removable” stresses. The following are characteristic features of the procedure: staged pattern of the calculation, which is constructed in a manner so as to account for various influences exerted on the deformation of the mass by stresses acting prior to the opening of a working and the additional stresses that develop during this opening, as well as consideration of technogenic changes in the properties of the soils. The computational procedure is accompanied by examples with various initial and boundary conditions. |
