Effects of confinement on rock mass modulus: A synthetic rock mass modelling (SRM) study
Journal of Rock Mechanics and Geotechnical Engineering, 2018 The main objective of this paper is to examine the influence of the applied confining stress on the rock mass modulus of moderately jointed rocks (well interlocked undisturbed rock mass with blocks formed by three or less intersecting joints).

Engineering Reports, Volume 8, Issue 3, March 2026.The Bilaspur region lies in a highly seismic zone, requiring special attention for infrastructure development like tunnel construction. Rock strength in the area is low, posing challenges for stable tunnel design. RMR values range from 21 to 30, categorizing the rock mass as Poor, requiring robust support measures.

Data‐Driven Satellite Drag Modeling Without Dynamic Knowledge of the Atmosphere
Space Weather, Volume 24, Issue 2, February 2026.Abstract Increasing congestion in low Earth orbit (LEO) from new satellite deployments and a growing debris population has made accurate orbital trajectory prediction essential for anticipating and avoiding potential collisions on a regular basis. Atmospheric drag is usually the dominant source of propagation error across much of LEO, especially during

Journal of Rock Mechanics and Geotechnical EngineeringThe deterioration of unstable rock mass raised interest in evaluating rock mass quality. However, the traditional evaluation method for the geological strength index (GSI) primarily emphasizes the rock structure and characteristics of discontinuities. It
