Abstract

The rheological behavior of salt rock is studied by both uniaxial and triaxial relaxation tests. In order to investigate the relaxation behavior of salt rock, stepwise relaxation tests were performed after the sample had been subjected to different pre-relaxation creep strains and confining pressures. Results show that the lateral strain was almost constant during relaxation. Stress relaxation decreases with increasing confining pressure. The pre-relaxation creep strain very greatly affects the relaxation behavior of salt rock.
