Water inrush (WI) is one of the most dangerous geological disasters in underground engineering, with significant human casualties and economic losses. To prevent and control WI disasters, great efforts have been made to address WI mechanisms for more than half a century. In particular, the seepage instability theory is hitherto one of the most widely used theoretical models. This theory portrays that the seepage system will undergo structural instability when the initial values of permeability and boundary pressure meet certain conditions, which manifests that the permeability parameter is one of the most valuable indicators to unveil WI mechanisms. However, rock permeability is determined by its internal structural characteristics, which can be affected by water chemical composition, stress environment, and temperature. In this regard, it is of great necessity and importance to facilitate a better understanding of the holistic impacts of multi-field coupling on rock internal structure and deformation failure characteristics.
This Research Topic aims to initiate a global forum for presenting and disseminating the latest advancements of WI mechanisms, which entails the characterization of physical and laboratory tests, 3D reconstruction of rock internal structure, numerical approaches, theoretical models under multi-field coupling, and filed date analysis methods.
This Research Topic encourages submissions of Original Research and Review articles to underscore groundwater-induced geological disasters in underground engineering. Key themes include, but are not limited to:
• Rock deformation and failure mechanism under multi-field coupling
• 3D reconstruction and quantitative characterization methods of pore and fracture network in rock mass
• Theoretical, experimental, and/or numerical investigations on permeability evolution law of rock under multi-field coupling
• Theoretical, experimental, and/or numerical investigations on WI mechanisms in underground engineering
• Theoretical, experimental, and/or numerical investigations on other hazard evolution mechanisms induced by groundwater
