Excess pore pressures which develop during thawing of frozen fine-grained subgrade soils
Methods are presented by which excess pore pressures before application of any external loads can be calculated within subgrade during and after thawing; methods are based on premise that rate of thawing and rate of liberation of excess pore water decrease with increasing thawing depth and flow rate remains constant; thawing rate can be calculated from general differential equation which governs one-dimensional unsteady heat flow; relationship between initial pore pressure and bearing capacity of flexible highway and airfield pavements.
