STRENGTH AND DEFORMATION CHARACTERISTICS OF SOFT SEDIMENTARY ROCK UNDER REPEATED AND CREEP LOADING

The effects of cyclic loading on soft saturated porous rock have been investigated. A typical phenomenon is so called cyclic fatigue in which a material fails at a stress level lower than its static strength. Deformation, strength and behaviour of pore pressure under quasi-static and cyclic loading were studied in undrained test conditions. In addition, creep tests were conducted in order to know the long-term strength. The sample used in the experiments is porous soft tuff whose unconfined compressive strength is about 16 mn/M squared. Laboratory experiments have been performed to know the correlation between creep, cyclic loading and conventional strain-rate constant tests. The concept of complete stress-strain curve was evaluated. The number of the covering abstract of the congress is TRIS no. 385148. (Author/TRRL)
