Abstract Understanding the dynamic characteristics and time-dependent damage of rocks under water-rock interactions is crucial for mitigating deep-seated rock engineering hazards. To investigate the impact of water-rock interaction time on the dynamic impact compression characteristics and damage properties of granite，impact compression tests were conducted using a split Hopkinson pressure bar(SHPB) system on specimens subjected to varying immersion time. The results indicate that water immersion treatment enhances the sensitivity of granite strength to loading rates. Specifically，at lower loading rates，there is a linearly negative correlation between the strength softening factor and immersion time. Furthermore，optical microscopy，atomic force microscopy，plasma mass spectrometry and nuclear magnetic resonance techniques were employed to observe surface and internal microstructural changes in granite immersed for durations of 0，2，4，and 6 months. Optimization of the pore damage evolution model revealed that the pore damage threshold was not exceeded within the 6-month immersion period. Finally，Lastly，quantitative analysis of the temporal aspects of water-rock interactions distinguishes between chemical and pore damage mechanisms. The results indicate that physical and chemical interactions jointly promote pore development in granite，albeit with contrasting temporal behaviors: chemical interactions decelerate over time, whereas physical interactions exhibit an opposite trend.

Key words： rock mechanics granite water-rock interaction dynamic mechanical characteristics damage evolution temporal behaviors
