Special Issue Information

Dear Colleagues,

This Special Issue will focus on the impacts of construction-induced disturbances in underground engineering on the surrounding environment and existing structures. In underground engineering, symmetry is often reflected in the geometry of underground structures, support systems, and construction layouts, while construction-induced disturbances may induce symmetric or asymmetric patterns of ground deformation, stress redistribution, and structural response. Therefore, the study of construction-induced disturbance mechanisms is closely related to the concept of symmetry in engineering systems.

This issue welcomes contributions addressing theoretical, experimental, and numerical studies related to environmental disturbance analysis caused by underground construction activities, including shield tunneling, excavation, foundation pit excavation, and underground space development. Particular attention will be given to topics such as ground settlement evolution, pore water pressure response, soil liquefaction behavior, dynamic interaction between soil and structures, and the mechanical performance of tunnel linings and joints under complex loading conditions.

Advanced computational approaches, such as finite element methods, discrete element methods, peridynamics, and coupled multi-physics simulations, are especially encouraged. Additionally, interpretable AI methods, especially physics-informed deep learning, have shown great promise in combining computational modeling with the increasing availability of monitoring data from engineering projects, enabling a data-driven and physics-guided paradigm for engineering problems. This Special Issue aims to provide a platform for discussing innovative methods and practical solutions for understanding disturbance mechanisms, improving structural safety, and promoting resilient and sustainable underground infrastructure development.

Reliable assessment of tunnel face stability in rock masses containing persistent joints remains challenging because existing analytical methods generally neglect the influence of joint orientation. This study develops an equivalent analytical model that incorporates joint orientation into the limit analysis framework by modifying rock mass parameters. The proposed model explicitly considers joint orientations from 0° to 90°, enabling anisotropic joint effects to be efficiently represented within the analytical solution. Validation against numerical simulations demonstrates high prediction accuracy with substantially improved computational efficiency. Parametric analyses reveal that joint orientation is the primary factor controlling tunnel face stability, producing a symmetric M-shaped variation in stability and identifying the most unfavorable joint orientations. Rock mass quality, tunnel buried depth, and excavation-induced disturbance also significantly influence stability. The proposed model provides a rapid and practical approach for tunnel face stability evaluation in jointed rock masses, offering valuable support for tunnel design and construction. Full article

The collaborative load-bearing behavior between the rock mass and support is critical for tunnel support design. This study proposes a strain-softening analysis method for circular tunnels during construction and presents an efficient solution strategy, termed the “Support Load Approximation Strategy” (SLAS), to solve the collaborative load-bearing problem. The rock mass is assumed to be isotropic, following the Mohr–Coulomb criterion, under hydrostatic stress conditions. During the stepwise calculation, a new ring is automatically added at each step, and the positions of all previous rings are updated, with elastic or plastic formulations automatically selected based on the state of each ring. The GRC and plastic radii (Rp and Rs) curves obtained by the proposed method show excellent agreement with existing benchmark results, with relative errors of 3.73% for the GRC, 1.47% for Rs, and 3.40% for Rp, confirming the correctness and accuracy of the proposed algorithm. Furthermore, when compared to the Incremental Support Load Method (ISLM) and the binary search method, SLAS improves computational efficiency by 14.2 times and 67%, and accuracy by 70% and 53%, respectively. When higher precision is required, SLAS maintains an efficiency gain of 82.8 times over ISLM with comparable accuracy. Compared to traditional elastic-plastic analysis methods, the proposed approach simplifies the computational process, reduces complexity, offers both high accuracy and fast computation speed, and serves as a practical tool for tunnel engineering support design.
