Rock Mass Classification and Probability of Failure in Determining Slope Stability
Abstract
Abstract. Research on slopes is always experiencing development along with development of science and many cases of slope instabilty in the field. Rock slope found in most of the roads, often experience instability caused by rock mass conditions and external factors such as water and seismic activity. The purpose of this research is to analyze slope stability using two approaches, that is rock mass characterization and numerical modeling to calculate safety factor and probability of failure. The result of this research is slope 1 more stable than slope 2 with each value 6.03 and 2.02 with each probability of failure 0% and 0.48%. Result of numerical modeling is directly proportional to the rock mass characterization using RMR and GSI which classifies the rock mass on slope 1 in good condition, and rock mass on slope 2 in fair condition. The causes of the differences on the level of stability on the two slopes will be discussed further in this paper.
