Engineering Applications in Permafrost Areas 487 Frost heave forces on embedded structural units
Large-scale model studies of frost heave forces acting on horizontal, vertical, and inclined members embedded in a silt were carried out under frost penetration rates ranging from about 4 to 75 mm per day. Maximum adfreeze stresses in the range of 150 to 350 kPa under varying rates of frost penetrat...
