Special Issue Information

Dear Colleagues,

Geo-disasters, such as landslides, debris flows, rock collapses, floods, etc., are constant threats to the safety of people's lives and properties. Most geo-disasters are induced by a coupling interaction between geo-materials and geo-fluids, especially groundwater and surface water. Thus far, great efforts have been made in geo-disaster evaluation and accident prevention, but they still cannot be accurately forecasted. Therefore, geo-fluids make geo-disasters an extremely challenging problem.

To prevent potential damage, experiments and field monitoring are always included in the study of geo-disasters. However, the literature indicates that studies of these mechanisms remain inconclusive due to complex geological circumstances, environmental conditions, and inducing factors. Traditional theories of dynamic mechanics, analysis methods, and detecting technologies still lag behind engineering practice, and thus, hazard mechanisms must be determined. To this end, the urgent need for the detailed and systematic research on the effects of geo-fluids and hazard mechanisms is essential. This Special Issue aims to publish original research and review articles about the influence of geo-fluids and hazard mechanism analysis. In this Special Issue, experiments and field monitoring are encouraged, as well as numerical modeling. Papers submitted on new and emerging topics within the general discipline are also encouraged. We prefer comprehensive, innovative, and ground-breaking research findings. Thus, theoretical papers are welcome, and practice-oriented papers are particularly encouraged.

Fractures are widely distributed in karst areas, and when flow rates are high, they exhibit complex nonlinear behavior that cannot be accurately described by Darcy’s law. In this work, a hydro-mechanical coupling model based on a discrete fracture network is proposed to predict tunnel water inflow, accounting for the impact of non-Darcy flow. The model’s feasibility has been validated by comparing it with experimental results and the field measurements of flow rates at the Bodaoling Tunnel in Guizhou, China. The results show that Darcy flow tends to overestimate water inflow by approximately 25% compared to non-Darcy flow. The non-Darcy effect grows with the increase in initial fracture width and empirical constant q. When q exceeds 8.77 × 10−6, the growth rate of the Forchheimer number along the fracture width slowed down, and the inhibitory effect of non-Darcy flow on flow became gentle. Additionally, in a complex fracture network, the inflow rate limited by non-Darcy flow at one point drives the water flow through a connect fracture to another point, which increases the difficulty in water inflow prediction. This work highlights the importance of non-Darcy flow and fracture networks when accurately predicting water inflow in tunnels. Full article
