Water Inrush Mechanism and Treatment Measures in Huali Highway Banyanzi Tunnel—A Case Study

In the process of tunnel construction, water inrush disaster is one main engineering geological disasters. karst strata, different types water-bearing structures or bodies develop and occur in soluble rock layer, excavation easily forms new drainage channels, resulting tunnel. Based on project Huali Highway Banyanzi Tunnel, this paper studies characteristics, mechanism, treatment measures According to basic data, combined with field investigation, data monitoring, radar detection, tracer test, numerical simulation, characteristics hydrogeological conditions surge were investigated analyzed. addition, mechanism was further summarized. Moreover, water-gushing management are optimized verified based spraying mechanism.
