This thesis put up the freezing-thawing mechanics of soft rock basing on the frozensoil which has developed. The problems involved and proposed problems need to solve have all pointed out.
Supposing the defects as the initial crack, using the theory and testing method of fracture mechanics, the nonlinear fracture process and character of frozensoil are investigated.
