Study on resistance to deformation of artificially frozen soil in deep alluvium;

The loading and unloading triaxial tests were carried out on the deep frozen clay at four temperature gradients using the method of freezing before K0 consolidation,and attenuation law for deviatoric stress as well as deviatoric stress increasing rates in the process of loading and unloading was investigated.

The results indicated that (1) the centers of sandstorm are always corresponding to the minimum center or the relative smaller area of frozen soil depth, which means that the less (more) frozen soil depth is, the more(less) sandstorm days are; (2) air temperature is the.
