Abstract: By analyzing the property of frost heave in the aeolian soil, thispaper proposes a fractal interpolation method to study theone-dimensional problem offrost heave in frozen soil.It is found that the frost heave curve hasa good self-similarity, and the fractal theory can be used to describethe frost heave curve. The fractal dimension can represent thecomplexity and the non-linear property offrost heave curve, which is important for understanding theprocess of frost heave on the aeolian soil.
