The present invention discloses the application of a fluorine-containing polymer in the preparation of a transparent frozen soil, which is used as a transparent solid material while in the preparation of a transparent frozen soil, wherein the fluorine-containing polymer is Teflon AF 1600 produced by American DuPont Company, with the refractive index of 1.31 and the density of 2.1-2.3 g/cm3, and are particles with the particle diameter of 0.25-2.0 mm or particles with the particle diameter ≦0.074 mm, and its particles have irregular shape. When said fluorine-containing polymer of the present invention is used as a transparent solid material for preparing a transparent frozen soil, the prepared transparent frozen soil has high transparency, low price, no toxicity and no harm, and good similarity with the properties of the natural frozen soil body, can widely substitute natural frozen soil, is used for simulating complicated geological conditions, and is effectively used in model tests in the geotechnical engineering. |
