The rise and fall of reservoir water level will make the water storage environment of bank slope rocks different at different heights and water levels, and the types of water rock interaction are also different. Based on this, the deterioration test of rock mechanical properties of bank slope in water rock interaction zoning was carried out. The results show that the compressive and tensile strength of rock samples decrease with the increase of test cycle, showing a deterioration trend from fast to slow. With the advance of water rock interaction cycle, the shear failure characteristics become more and more obvious in the compressive and tensile tests of rock samples; The microstructure of rock sample gradually transits from dense to loose, porous and multi crack structure. Under different water rock interaction, the mechanical properties and microstructure deterioration degree of rock samples ranks thermal wet cycle > dry wet cycle > long-term immersion. The results can provide ideas for the long-term stability analysis of bank slope based on water rock interaction zoning.
