Calculated diagrams of a deformed soil mass at transfer of external and internal power influences to array

The analysis of the existing laws of stress distribution in the soil from external and internal force effects. It is shown that the existing classical solution of the stress-strain state of an elastic half-space from exposure to external and internal influences to use in calculations without additional assumptions. In this regard, we propose a method of determining the stress-strain state (elastic half-space) of the soil from external and internal influences transmitted via limited in terms of the area that gives the opportunity to determine the state of stress (elastic half-space) of the soil with regard to real values, going from ∞ no regular assumptions. Determination of deformations of foundation was based on the solution of one-dimensional problem of compacting of the soil massif limited to the thickness proposed by prof. M. Gersevanov. In the normative documents, approved by the USSR state Committee for construction (SNiP) there are two calculation schemes, which were determined by precipitation of the bases and foundations: 1. Linear deformable elastic half-space with a conditional limitation of the compressible strata (elementary method of summation) and the calculated scheme in the form of linear-deformed layer (for major in terms of the bases b ≥ 10 m). To solve this problem, we proposed a method for determining the capacity of the compressible strata with the assumption that soil mass will start to show deformation properties (deformation) when the ground pressure (σ) will exceed the calculated resistance of the soil mass, that is, performs the equilibrium condition σ ≥ R. On this basis it is shown that underground structures are carried out by way of "trap hole" and "wall in the ground", do not show the residue grounds.
