Abstract

For the stability of rock salt cavern during the washing process, the research on the relationship between the dissolving mechanism and mechanical effect of rock salt is necessary. Through analyses on rock salt dissolving mechanism, and rock salt dissolving effect with and without mechanical effect, difference between rock salt dissolving model with and without mechanical effect has been studied. It can be concluded that rock salt dissolving mechanism with and without mechanical effect is same, but with mechanical effect, especially after the plastic strain and cracks have been produced, difference between the dissolving effect with and without mechanical effect has been existed; compared with the parameter “diffusion coefficient” D on the dissolving model without mechanical effect, the new conception “equivalent diffusion coefficient” D* has been proposed to describe the macro-dissolving speed of rock salt with mechanical effect under the assumption that dissolving action face has not been changed during the dissolving process. D* is a variable of the equivalent plastic strain and dissolving time; based on rock salt dissolving model without mechanical effect and the new concept D*, rock salt dissolving model with mechanical effect has been built; through analyzing the datum of uniaxial compression meso-mechanical test under the coupled mechanical-dissolving effect, the method to calculate D* has been proposed, and the relationship between axial plastic strain, dissolving time and D* has been obtained. The achieved results can provide a research foundation for the further analyses on coupled mechanical-dissolving mechanism of rock salt.
