摘 要：<正> Based on the method of torsional creep, the creep laws of an anhydrite specimen are studied in this paper. When a shearing stress applied to the specimen is less than a value, only the primary stage takes place, How -ever, when the shearing stress is more than another value , all the three stages of a creep curve,i.e. primary, steady -state and accelerated are exhibited. The long-time strength of the anhydrite specimen is acquired; it is 2.77 MPa, and it is only 66% of the instantaneous strength of the anhydrite specimen.
