This article introduced a new method, the mechanical analysis of the semi-infinite linear deformation body in the layered space, i.e. by the the-roy of double-layered foundation, for the calculation of normal frost heaving force in seasonal frozen districts. In calculation, it is assumed that the temperature of frozen ground changes with its depth(equation l),and the relation of elasticity modulus of frozen soil and unfrozen soil to the depth and stress condition in the soil is expressed by equation 4 and e...
