地质雷达与跨孔电阻率CT成像法协同在岩溶塌陷及富水区勘查中的应用

Application of Geological Radar and Cross-hole Resistivity CT Imaging Method in Karst Collapse and Water-rich Area Exploration

随着我国城市化进程的加快,浅层岩溶塌陷及富水区引起的地质灾害日益严重,直接威胁人民生命财产安全,阻碍国家经济发展,尤其在道路、隧道、地铁等市政工程建设方面,造成的人员伤害和经济损失更为巨大,所以探明岩溶塌陷区及富水区尤为重要,且勘查精度要求较高。为此,本文尝试利用地质雷达浅层探测分辨率高与跨孔电阻率CT成像法探测深度较深的特点协同实施,探明岩溶塌陷及富水区分布情况,取得了较好的效果,提供的地质成果精度高,满足后期治理使用的要求。

With the acceleration of urbanization in China,shallow karst collapse and geological disasters caused by water-rich areas are becoming more and more serious,directly threatening people's life and property safety and national economic development,especially in the construction of municipal projects such as roads,tunnels,and subways.Personnel injuries and economic losses are even greater,so it is particularly important to identify karst collapse zones and water-rich zones,and the exploration accuracy requirements are high.To this end,this paper attempts to use the characteristics of shallow depth detection of geological radar and the deep depth of trans-hole resistivity CT imaging to detect the distribution of karst collapse and water-rich areas,and has achieved good results.The geological results are highly accurate and meet the requirements for later use.
