Abstract

Thaw weakening of frost-susceptible, thawing soils in cold regions is a problem affecting strongly on the deformations and stability of pavements, slopes and other engineering structures. In this paper, the freeze-thaw process is described in order to determine the parameters important for the development of pore pressure during thaw. For the practical assessment of the field measurements, the start and end of thaw should be estimated, as well as the period of stiffness recovering after thaw. The subgrade modulus depends both on the thickness of the thawed layer and on the material modulus of the thawed material. In the back-calculation, the stiffness should be described in terms of effective stresses.
