Abstract：In order to study the frost deformation of rock under subfreezing temperature，strains of dry and saturated rock samples at low temperature were tested by strain gauge method. The result proves that dry rock samples behave as linear elastic characteristics during one freeze-thaw cycle，while the deformation of saturated rocks experienced four stages as follows：thermal contraction stage，frost expansion stage，thawing contraction stage and thermal expansion stage，and the residual strains were evident. Based on the test results，frost expansion deformation of moist rock at low temperature was analyzed. Ultimately，the conclusions were applied to a tunnel in cold region and the frost deformation characteristics of tunnel is studied. Besides，the distribution of unfrozen，freezing and frozen zones under certain frozen condition are sketched.
