DEFINING METHOD OF BEARING CAPACITY AND SETTING OF SOIL FOUNDATION AND PEAT BED Russian patent published in 2009 - IPC G01N3/00 

FIELD: construction.

SUBSTANCE: invention pertains to the field of construction, in particular, to defining methods of settings and static bearing capacity of soil foundations and peat beds. The method consists in definition of physical-mechanic parameters: internal friction angle cp, c - specific adhesion and γ₀ - volume weight uniform at depth of the soil foundation and anisotropic peat bed, computation of the mean pressure value applied to the foundation through the totally smooth flexible and rigid critical dimensions stamp (b_cd, d_cd) of various forms and prominence, corresponding to its bearing capacity passing through interphase condition, and in computation of stamp setting corresponding to this pressure from the formula of soil foundation "one-dimensionally - deformed semispace", and peat - from the formula of Fuss-Vincler model "of local elastic strains". Thereat more precise relations of computations of the bearing capacity of the peat bed under the totally rigid plain banded stamp are settled, along with new relations of the bearing capacity and corresponding soil foundations and peat bed under totally flexible and rigid stamps made of cylinder-shape (with the length l=∞ and at l/B_cd-varir, at B_cd=const and at constant area of contact patch F=const), under the flexible cylindrical tube with bent ends, flexible upright tore, flexible ellipsoid and hard sphere, under plain flexible quadrate and narrow short cylinder.

EFFECT: definition of clear calculated relations of the bearing capacity and foundation settings when passing their interphase state.
