Vector diagrams of strength and their use for evaluation of stability of jointed rock masses around mine workings
Abstract
The paper presents the methods for obtaining the rector diagrams of strength of jointed rock mass. The method is based on a new concept, and permits to determine separately the strength of the continuous members and also the strength parameters along the weakening planes; then, the overall influence of the strength indices on the failure process will be defined, taking into account the spatial relative position of the weakening planes and stress tensor. Some examples are given, showing how the vector diagrams are used in practice for evaluation of the mechanical properties of rock mass including its ultimate strength.
