Supporting evidence — 4 representative gaps

• Investigation of tunnel–soil–structure interaction under dynamic loading in non-homogeneous soils: case study of Catania, Sicily, Italy (2026) · Bulletin of Earthquake Engineering · doi

  While previous research has extensively examined tunnel–soil interaction under seismic loading, the combined influence of soil heterogeneity and the dynamic interaction between underground tunnels and aboveground structures remains insufficiently explored.

• Excavation-induced stress release and ground improvement depth in normally consolidated rock, transitional rock, and soil media (2026) · Bulletin of Engineering Geology and the Environment · doi

  The lack of a systematic analytical description of the depth-dependent evolution of excavation-induced stress-release. The need for a simplified analytical framework for evaluating excavation-induced stress redistribution and defining preliminary ground-improvement depth envelopes in normally consolidated geomaterials.

  The spatially extensive nature of excavation-induced deformations. The need to evaluate the mechanical response of geomaterials and the influence of ground deformation and foundation performance beneath excavation bases. The lack of a systematic analytical description of the depth-dependent evolution of excavation-induced stress-release.

• Effect of Excavation Sequence on Uplift Deformation of Underlying Existing Metro Tunnel (2021) · Journal of Performance of Constructed Facilities · cited 29× · doi

  Although an appropriate excavation sequence contributes to minimizing the excavation-induced impact on the underlying existing tunnel, few studies have focused on the comparison of the excavation sequence for engineering projects in practice.
