Under the analysis frozen earth forming process and the fabric premise

embarks from the frozen earth viewing carefully structural feature

regards as the transverse view isotropic solid dielectric which the frozen earth is composed of the ice layer and the dry and hard soil layer caking. According to the theory of composite materials mechanics

in outside the frozen earth isotropic surface and the surface elasticity coefficient and the Poisson’s ratio are obtained. Based on the Tsai-Wu criterion

the transverse isotropic frozen soil strength is perdicted. According to the empirical data

the influence of the different components on the frozen soil elastic constant and strength is analyzed. In the project application

according to the ambient temperature and the soil texture

whether there is the system moisture content supplies

the temperature drop speed and the freeze speed whether synchronization

the frozen soil stress direction and the freeze title page direction special details selects then

thus the indoor and outside test number is reduced largely. Has laid the foundation for the frozen soil project numerical calculation

to further understand that the frozen soil mechanics characteristic so as to provide the theoretical basis.
