Research on the Comprehensive Forecasting Technology of Karst-fractured Groundwater in Tunnel Geological Disaster Early Warning System
Karst-fractured groundwater is widespread in karst areas,and the movement of karst-fractured groundwater is the fundamental driving force behind geological disasters such as collapse in karst areas.Effective prediction of karst-fractured groundwater can provide essential safety assurance for tunnel engineering.Consider-ing the characteristics and distribution patterns of karst-fractured groundwater,this paper enumerated three main methods for advanced prediction of geological disasters related to karst-fractured groundwater:TSP,geological ra-dar,and EH-4 high-frequency magnetotelluric sounding.Utilizing practical engineering cases,the engineering philosophy,data management analysis and applicability of these methods were thoroughly analyzed.Through com-parative studies,the strengths and weaknesses of these three early prediction technologies were comprehensively as-sessed.This research will contribute to refining the technical means of the tunnel geological disaster early warning system,providing technical support for the sustainable development of karst regions.
