Progressive failure in stratified and jointed rock mass
Summary This paper describes a mathematical model for analyzing progressive failure in a stratified and jointed rock mass dipping parallel to the slope face. The relationship between the necessary support forces and permissible displacement in the rock mass is discussed. An analytical expression is provided for the minimum required support force corresponding to a critical displacement. This expression is used to evaluate the potential of unstable failure propagation. The effect of time on progressive failure is considered by using a simple rheological model for joints. A case study, involving an excavation in a stratified medium, is used to compare model prediction with monitored performance.
