PROBABILISTIC APPROACH FOR THR ANAYSIS OF ROCK EXCAVATION STABILITY

摘要

The deterministic description of rock excavation stability with a safety factor is firequently insufficient and,sometimes,misleading.The applications of the probabilistic analysis to determine the likelihood of a rock excavation failure have been proposed by many researchers.The probabilistic analysis will lead to a better understanding of excavation stability and provide more complete information on the safety and stability of rock excavations.
