תקציר	Geomechanical modeling is the numerical simulation of stress and deformation in rock masses, integrating rock properties, pressure conditions, and geometric constraints. Rooted in classical mechanics (Coulomb, Mohr) but modernized by finite element and finite difference methods, this approach is essential for well integrity assessment, reservoir compaction prediction, and stability evaluation of slopes and excavations. Models link subsurface geology to rock mechanical behavior.	Rock mass classification is the systematic assessment of rock quality and mechanical behavior in engineering geology, combining field observations of jointing, weathering, and strength into a numerical index. Pioneered by Bieniawski (RMR system, 1974) and Barton (Q-system, 1974), these methods enable rapid site assessment and guide design of excavations, dams, and slopes. Classification bridges the gap between small laboratory samples and large field-scale behavior.
