摘要运用应变片法测试低温环境下饱和及干燥岩样的低温应变特征，研究岩样冻胀融缩效应，给出严格的岩石冻胀变形规律。试验结果表明：一个冻融循环内，干燥岩样变形表现为线弹性特征，而饱水岩样的变形大致经历冷缩、冻胀、融缩、热胀等阶段，并产生残余应变。依据试验结论，运用理论分析方法研究岩石冻胀应变，并将其运用于工程实例，模拟寒区隧道冻胀变形特征，并得出一定冻结条件下围岩未冻区、正冻区和已冻区的分布状况。

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.

Key words： rock mechanics frost deformation freezing pressure water content phase transition frozen ratio
