Abstract: The dissolving mechanism of rock salt with and without stress is same, but difference between them is the variation of the dissolved surface. Dissolving model of rock salt without stress is set up based on the analysis of dissolving mechanism. By way of analyzing the difference of dissolving mechanism of rock salt with and without stress, equivalent dissolving coefficient is proposed to describe the macro-dissolving speed of rock salt under the stress, based on which dissolving model of rock salt under the stress is set up. The method to calculate the equivalent dissolving coefficient is proposed based on the uniaxial meso-mechanical test data under the coupled mechanical-dissolving effect, and the relationship among axial plastic strain, dissolving time and equivalent dissolving coefficient is obtained. The results can provide an important basis for the further analysis of coupled mechanical-dissolving mechanism of rock salt.

Key words: salt rock, dissolution, effect of stress, equivalent dissolving coefficient
