| 摘 要： | 隧道施工完成后用常规方法很难对衬砌质量做出系统评价，地质雷达利用超高频脉冲电磁波探测目标介质的介电常数，很容易掌握砼衬砌结构的厚度、衬砌周围回填及空隙情况，围岩断层裂隙构造情况等，为工程技术评价提供依据。文章以实例，介绍了利用地质雷达对隧道进行检测所使用的仪器、工作参数及地质雷达资料处理解释步骤，并通过对几幅典型雷达图像进行分析介绍了不同异常结构在雷达剖面上的反映。

| Abstract: | It is hard to make a systematic assessment of lining quality by the use of routine methods after tunneling is completed. The geological radar set out target medium's inductivity by the use of ultra high frequency pulsed electromagnetic method to detect concrete liner thickness, backfilling and voidage status around the liner, as well as faulting and fracturing of surrounding rocks etc. to give engineering technicians for a basis of evaluation. By the use of examples, the paper introduced instruments, operating parameters, and data processing, interpretation procedures of the method, analyzed and introduced different anomalous structures' representation on radar profiles by made a convenience of some typical radar images. |
