| Abstract: | By analyzing the property of frost heave in the aeolian soil, this paper proposes a fractal interpolation method to study the one-dimensional problem of frost heave in frozen soil. It is found that the frost heave curve has a good self-similarity, and the fractal theory can be used to describe the frost heave curve. The fractal dimension can represent the complexity and the non-linear property of frost heave curve, which is important for understanding the process of frost heave on the aeolian soil. |
