Slope stability analysis using Universal Distinct Element Code (UDEC) method

Abstract

Slope stability analysis was conducted using the Universal Distinct Element Code (UDEC) technique in this research. This technique stimulates the spread of stress waves in the jointed rock mass owing to dynamic loading caused by the blast. Simulation is a vital component of the slope stability analysis, as it generates a model called discontinuum capable of simulating the movement of fragments owing to the burst of production. Besides, the discontinuous codes used in this analysis may duplicate the entire method of fragmentation of the rock from fracture to fragment throw. This discontinuous analysis can also simulate joints and porosity attributes in a rock mass.
