Abstract: The influence of confining pressure on the post-peak softening rule of soft rock has been researched. Based on the stress-strain curve of triaxial experiments, the softening law of physical property parameters is studied; and a post-peak softening numerical model is established by means of the technique of determining the equivalent cohesion and friction and the curve-fitting. At last, the numerical simulation based on the model approximately matches the triaxial experiments.

Key words: confining pressure, post-peak softening, numerical model
