ABSTRACT

This paper proposes a method for restricting or eliminating frost heaving known as “stationary frost heaving” this is commonly seen in the thermally quasi-stable. The heaving amount of stationary frost heaving of frost susceptible soil is about 70 to 80% of the total heave amount. A necessary condition for stationary frost heaving is clarified in this paper. The condition lays the groundwork for the frost heave restriction method. The method changes the thermal boundary condition up to the net heat flow at the freezing frost becomes zero. The effectiveness of this method is verified by frost heaving tests. Frost heaving observed after the application of the method is found to be due to another frost heaving action called “long-term frost heaving . This frost heaving has already been studied and is considered ignorable as engineering factor because of its small heaving amount.
