Abstract
Consolidated undrained triaxial tests were performed on a diatomaceous soft rock to investigate the effect of a single joint with different inclinations on the residual strength characteristics.
Measurements of the stress strain behaviour show that the residual strength of intact rocks (no joint) coincides with that of precut rocks having a single joint and the strain softening behaviour is influenced by the magnitude of consolidation pressure. The residual strengths of overconsolidated intact and precut specimens are little affected by the rate of strain and in the comparisons of the rate of creep strain, there is no significant difference between the intact and the precut specimens.
