Abstract
A probabilistic-based approach is proposed to incorporate Fisher's constant in the stability analysis of rock blocks. To account for the uncertainty reflected by the sample dispersion, data are generated systematically around each mean discontinuity normal, based on its Fisher's constant. The probability of rock block failure at a certain location and the largest possible block volume are determined in a logical manner. A microcomputer program has been developed to automate the analysis, and examples are shown. In addition, risk mapping plots are presented to enable visual selection of an optimal route for excavation from one location to another. -from Authors
