Abstract

Способ определения морозного пучения грунта при промерзании сезоннопротаивающего слоя, включающий бурение скважины перед началом его промерзания, отбор образцов грунта, измерение глубины сезонного протаивания ξ, определение на образцах плотности сухого грунта ρd,th, отличающийся тем, что дополнительно бурение скважин производят после промерзания сезоннопротаивающего слоя, на образцах дополнительно определяют плотность сухого грунта после промерзания сезоннопротаивающего слоя ρd,f, а величина пучения определяется по формуле: A method for determining frost heaving of soil during freezing of a seasonally spreading layer, including drilling a well before freezing, taking soil samples, measuring the depth of seasonal thawing ξ, determining the density of dry soil ρd, th on the samples, characterized in that the wells are additionally drilled after freezing of the seasonally spreading layer , the samples additionally determine the density of dry soil after freezing the seasonally spreading layer ρd, f, and the heaving value is determined by the formula:
