Abstract：Based on the theories of geochemistry，mineralogy，petrology，geo-thermodynamics，plastoelasticity，a comprehensive analysis of the effects of stress on dissolution mechanism of salt rock is carried out. And it reveals that stress has its effect at multi stages by many manners，and so the dissolution mechanism under stress is different from that without stress：(1) stress shows its influence directly by inducing additional free energy in the halite solid，which can increase the activity or concentration at the solid/liquid interface；(2) stress shows its indirect influences by changing the depth h of the bund layer at the surface of salt rock solid，velocity u and pattern of fluid water，and effective interaction area of dissolution between solid and water. It is found that the dissolution mechanism of salt rock under stress is a positive feedback loop owing to the coupling of stress-dissolution，and the essential relations between stress and dissolution are that strain energy can increase the chemical potential energy difference between water and solid at the solid/liquid interface，which can accelerate the reaction of dissolution progress and so shows its effects on the dissolution mechanism of salt rock.
