Research on the Relationship of Frost Heaving Forces and Amount of Frost-Heaving again

The effect of surface amount of frost heaving on normal frost heave force in the new edition of《Design Specifications of Hydraulic Structures Against Ice and Freezing Action》(DL/T5082-1998) was discussed. The surface amount of frost heaving is an integral of frost heaving ratio along the full freezing depth. The normal frost heave force is an integral of soil frost heave stress at the freezing front along the range effected by a foundation. Therefore, it is no relationship between normal frost heave force and surface amount of frost heaving.
