摘　　要：文章探讨了地质雷达探测技术在复杂地质岩土勘察中的应用。此技术运用电磁原理发射与接收高频电磁波,借由地下介质介电常数差异成像以获取地质信息,具备高分辨率、快速且无损、结果直观等特性。复杂地质岩土勘察存在地层与岩土体复杂、地下水影响、岩溶滑坡隐患及环境人文制约等难题,地质雷达于岩溶溶洞和裂隙、滑坡体滑动面及内部结构、地下空洞、岩土体界面识别等方面应用良好,但在探测深度与抗干扰方面还有不足,未来有待结合其他手段完善工作。This article explores the application of geological radar detection technology in complex geological and geotechnical exploration.This technology uses electromagnetic principles to emit and receive high-frequency electromagnetic waves,and obtains geological information by imaging the difference in dielectric constant of underground media.It has the characteristics of high resolution,fast and non-destructive,and intuitive results.Complex geological and geotechnical investigations face challenges such as complex geological and soil layers,groundwater influence,hidden dangers of karst landslides,and environmental and cultural constraints.Geological radar has been well applied in identifying karst caves and fissures,sliding surfaces and internal structures of landslide bodies,underground cavities,and rock soil interfaces.However,there are also limitations in detection depth and anti-interference.In the future,it needs to be optimized and combined with other methods to improve the survey work.
