FIELD: physics.
SUBSTANCE: method for determining the bearing capacity of the peat deposit is to determine the physical and mechanical characteristics of the peat deposits deformed by the stamp of the upland or lowland type in a structured state: the ϕ° angle of the internal friction, C - the specific clutch, γ - volumetric weight in calculating the average value of the initial (first) critical pressure for peat deposits corresponding to the long-term bearing capacity of peat deposits of according to the scheme of A. Hauzeyla - S. S. Korshunova, where rA=AA+VA⋅ (P/F), P - the perimeter of the stamp area F, AA - the fast-acting elastic resistance of peat, VA - the long-term bearing capacity of peat deposits, and in the calculation of the average magnitude of the limiting pressure of corresponding to the time limit phase transition of the peat deposits deformed by the stamp with a characteristic processes of sharp sediment rise, strength reduction and possible loss of stability, review of work schemes of a peat deposit as a model of Fussa-Winkler "local elastic deformations", when the external medium pressure capabilities have resulted in where AV - the elastic limit of the bearing capacity and the VV - the temporal limit of the bearing capacity of peat deposits, counteracted by the resistance of the peat fibres to stretch and slice T along the perimeter P of the stamp, wherein for the peat deposits of the upland or lowland type the value of the initial (first) critical pressure and the critical pressure are calculated from the given ratios.
EFFECT: possibility of determining the physic mechanical characteristics of a peat deposit of the upland or lowland type deformed by a stamp in a structured state.
