Abstract
The present invention discloses a transparent frozen soil, which is prepared from a fluorine-containing polymer, ice particles and a colorless pore fluid by steps of preparing materials, blending, vacuuming, consolidating, and freezing. The fluorine-containing polymer is poly[4,5-difluoro-2,2bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene], with the refractive index of 1.31, the particle diameter ≦0.074 mm, and the density of 2.1-2.3 g/cm3. The present invention also provides the application of above transparent frozen soil in the frozen soil directional blasting model test and the frozen soil road embankment model thaw-slumping landslide test. The transparent frozen soil prepared by the present invention can well simulate the properties of natural transparent frozen clay, is effectively used in model tests in the geotechnical engineering, with accurate measurement results, and can realize the visualization of the internal deformation of a soil body, and it is low in the expense, and simple in the operation.
