摘要
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.
Abstract
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.
