Abstract For the purpose of researching the damage evolution law of granite residual soil under drying-wetting cycles，the uniaxial compression-resistivity testing system were used to test the resistivity-stress-strain curves of undisturbed samples under different drying-wetting cycles. Based on the resistivity testing data，the mechanical damage evolution model of granite residual soil during the uniaxial compression test was proposed. The test results show that the deformation process of the granite residual soil are divided into 3 different stages，corresponding to elastic，plastic and residual deformation stage. A positive linear correlation between values of initial resistivity and peak strengths is found during the process of 0–5 drying-wetting cycles. The damage evolution model based on resistivity can accurately describe the mechanical behavior of undisturbed soil samples under uniaxial loads. Through the application of the initial damage factor，the mechanical model can effectively predict the stress-strain curves of granite residual soil under drying-wetting cycles. The results provide a reference for the application of resistivity testing techniques in rock and soil mechanics.

Key words： soil mechanics granite residual soil uniaxial load drying-wetting cycle resistivity damage mode
