1. A transparent frozen soil, wherein the transparent frozen soil is prepared from a fluorine-containing polymer, ice particles and a colorless pore fluid by steps of preparing materials, blending, vacuuming, and freezing, and the dosages of said fluorine-containing polymer, ice particles and colorless pore fluid are calculated by the test conditions and the sample sizes; said colorless pore fluid is water, said fluorine-containing polymer is particles with the particle diameter of 0.25-2.0 mm, and its particles have irregular shape, and is poly[4,5-difluoro-2,2bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene], with the refractive index of 1.31, and the density of 2.1-2.3 g/cm3; the particle diameter of said ice particle is 0.1-0.5 mm; the physical properties of said transparent frozen soil are: density of 1.53-2.0 g/cm3, unit weight of 15-20 kN/m3, and relative density 20-80%; and the mechanical properties are: internal friction angle of 30°-31°, modulus of 8-61 MPa, and Poisson's ratio of 0.2-0.4.
