摘　　要：地质雷达可以从异常信息中准确判别并解释对应的岩溶不良地质现象,所以尤为重要。文章首先阐述了地质雷达的探测基本原理;其次研究了隧洞的岩溶类型及其地质雷达信号特征;最后结合工程实例对地质雷达信号进行了解译,并对岩溶类型进行了综合分析。研究结果表明,地质雷达法可有效应用于隧洞岩溶发育特征探测。Ground penetrating radar(GPR)can effectively detect common erosion fissure zones,karst caves,and water-rich karst pipelines during tunnel construction in karst areas.However,GPR images are often complex,making it particularly important to correctly interpret the corre-sponding karst geological phenomena from abnormal radar signals.This article first introduces the detection principle of GPR,then explores com-mon karst types in tunnels and their GPR signal characteristics.Finally,it interprets GPR signals based on engineering examples and comprehen-sively analyzes karst types.The research results show that GPR can be effectively applied to detect the characteristics of tunnel karst development.
