Abstract

This paper introduces an advanced failure criterion methodology that integrates intact and fractured rock properties within geotechnical domains, using a 3D Mining Rock Mass Model derived from geotechnical logging data. The approach incorporates rock mass strength, fracture frequency, and joint roughness conditions (JRC) at varied joint orientations. Strength parameters are calibrated with laboratory data and available back analysis data and used in stability analyses.

The methodology provides a more precise slope stability assessment than conventional techniques by spatially mapping rock bridges and discontinuities.

Case studies are presented to demonstrate the practical application in open-pit slope design.
