FIELD: construction.
SUBSTANCE: method to determine frost heave of soil during freezing of a seasonally thawing layer includes drilling of a well before start of its thawing, sampling of soil, measurement of depth of seasonal thawing ξ, definition of dry soil density in samples ρd,th. In addition wells are drilled after freezing of the seasonally thawing layer, on the samples they additionally define density of dry soil after freezing of the seasonally thawing layer ρd,f, and the heave value is determined in accordance with the given dependence.
EFFECT: reduced labour intensiveness of works, increased accuracy of determination of heaving value, provision of material intensity reduction.
