Research on the Comprehensive Forecasting Technology of Karst-fractured Groundwater in Tunnel Geological Disaster Early Warning System

岩溶裂隙水普遍存在于岩溶地区,其运动是造成岩溶地面塌陷等地质灾害的根本原因,有效的岩溶裂隙水预判技术能为隧道工程提供安全保障。结合岩溶裂隙水的性质、分布规律等特点,本文列举了TSP预报法、地质雷达、EH-4高频大地电磁测探三种主要岩溶裂隙水地质灾害超前预报方法。借助实际工程案例,对三种方法的原理、数据采集和处理及适用范围进行深入分析,通过对比研究,综合评价三种超前预报技术的优缺点,助力提高隧道地质灾害预警体系中的综合预报技术水平,为岩溶地区的可持续发展提供有效技术支持。

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.Considering 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 radar,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 comparative studies,the strengths and weaknesses of these three early prediction technologies were comprehensively assessed.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.
