In order to reflect the whole process of stress-strain of rock subjected to freeze thawing in the cold region under external force, this paper uses the theory of statistical damage mechanics and assumes that the strength of rock microelements obeys Weibull distribution. Then, according to the maximum tensile strain failure criterion, a damage model of rock subjected to freeze thawing in the cold region is established by considering the coupling effect of freeze thawing and load. The theoretical solution of the model parameters is deduced, and the damage model is verified by the test results and damage constitutive model of the predecessors. The evolution law of the total damage curve of the rock under different freeze-thaw cycles is discussed, and the model parameters are analyzed. Finally, the influence of the freeze-thaw cycle on the stability of tunnel engineering is calculated by the numerical simulation method. The results show that the model established in this paper can well reproduce the stress-strain curve of the rock and reflect the post-peak strength of the rock. The total damage evolution curve of the rock under different freeze-thaw cycles is S-shaped, and it can be divided into three stages: initial damage stage, accelerated stage, and complete damage stage. Weibull distribution parameters
