Special Issue Information

Dear Colleagues,

This Special Issue aims to showcase cutting-edge advances in multiphysics modeling and intelligent approaches in geotechnical and geological engineering, with particular emphasis on bridging theoretical innovations, computational methodologies, and practical engineering solutions, with a special focus on symmetry-related phenomena. Contributions are invited that investigate the mechanical behavior, stability, and performance of geotechnical systems, including underground structures, rock masses, energy storage facilities, and geotechnical infrastructure. Topics of interest include, but are not limited to, the following:

  • Geotechnical and underground engineering, including tunnels, foundations, slopes, and excavation systems.
  • Multi-physics coupled numerical methods for analyzing complex geomechanical, hydro-mechanical, and thermo-hydro-mechanical behavior.
  • Physics data-driven modeling, predictive approaches, and uncertainty quantification for geotechnical systems.
  • Machine vision-based intelligent perception, monitoring, and measurement of underground struc-tures and rock masses.
  • Rock mechanics and thermo-hydro-mechanical-chemical behavior, including fracture, damage, and failure mechanisms.
  • Intelligent grouting, seepage control, and stabilization technologies for enhanced geotechnical performance.
  • Energy geo storage and underground storage systems, including CO2, hydrogen, and thermal energy storage.

This study addresses a key limitation of conventional clay constitutive models, which often assume linear stress paths at low stress ratios and lack a systematic link between plasticity and yield surface shape. A symmetry-consistent bounding surface plasticity framework is proposed, introducing two shape parameters, Ψ and Ω, to control curvature and scaling of the yield surface under low stress ratios. The formulation preserves a unified, smooth yield function with continuous gradients, ensuring compatibility with standard numerical integration schemes. To enhance practical applicability, a three-level calibration strategy is established, ranging from direct triaxial interpretation to empirical correlations based on oedometer-derived indices. Model performance is validated against experimental data for clays with varying plasticity, demonstrating improved representation of curved stress paths without increasing formulation complexity. The proposed approach provides a transparent and reproducible extension to existing frameworks, bridging the gap between theoretical consistency and engineering-oriented calibration. Full article

The confined concrete box steel arch support—composed of box steel and core concrete with a geometrically symmetric double-chamber cross-section—is an innovative solution for effective deformation control in soft rock tunnels. To address the longstanding challenge of balancing accuracy and efficiency in numerical simulations of such supports, this study proposes an improved simulation method. Specifically, a compression-bending yield criterion for the steel–concrete composite structure was derived based on the plane section assumption and full-section plasticity criterion. This criterion was then embedded into a pile element via Fish programming to develop an improved pile element, enabling accurate simulation of the bending moment–axial force coupling effect. Verification results demonstrate that the derived yield criterion precisely captures the axial force–bending moment coupling behavior of the confined concrete box section. Numerical simulation data exhibit excellent consistency with the theoretical m-n curve, with the maximum deviation in yield axial force and bending moment not exceeding 10%. Compared with the solid element model, the improved pile element model shows differences of less than 6%, 13%, and 21% in key indicators of surrounding rock stress, deformation, and plastic zone, respectively—meeting engineering accuracy requirements. Notably, the mesh count of the improved model is only 5.5% of that of the solid element model, achieving over a 40-fold increase in computational efficiency. Furthermore, this study identifies section type and section size as the dominant parameters governing surrounding rock stability, providing valuable insights for the design and numerical simulation optimization of soft-rock tunnel support systems.
