Abstract: The equivalent material model experiment is one of the important methods to study the geotechnical engineering. Based on the similarity theory, the creep similar model of rock salt is derived by dimensional analysis method and the similarity criteria of the corresponding parameters are obtained. The aggregate of equivalent material includes the salt particles with different diameters and iron power, the adhesive of equivalent material includes epoxy and ethylene. The blending ratio settling for the creep similar model of Jintan rock salt is got by a great deal of material proportioning tests, which is the solid basis for studying the distortion and breach of the salt caverns for storing oil or gas by equivalent material model test

Key words: salt rock, creep similar model, similarity criterion, equivalent material, proportioning test
