 This study investigates the response characteristics of a soil rock mixture under repeated freeze thaw action and its influence on the safety and stability of a dump slope in low-temperature environments. The paper carried out indoor freeze thaw cycles, uniaxial compression, and electrochemical impedance spectroscopy tests on a soil rock mixture taken from a graphite mine dump in Zhixi city, Heilongjiang province, China. The results showed that as the number of freeze thaw cycles increases, the mesopores inside the soil rock mixture gradually increase and the uniaxial compressive strength and peak secant modulus increase exponentially with the increase in the number of freeze thaw cycles. The failure mode was mainly tensile cracks followed by tensile shear cracks and the fewest compression shear cracks. The similarity and uniaxial compressive strength conformed to a good linear relationship with the number of freeze thaw cycles.
