摘要
地质雷达已被广泛应用于隧道工程中,但地质雷达在隧道工程探测过程中时常会遇到干扰因素,会导致雷达探测反射波波形堆积图异常,干扰波形覆盖了有效波形,严重影响后续的解译工作。文章将地质雷达在隧道工程中所遇的干扰划分为耦合干扰、施工干扰及特殊情况下的干扰三种类型,对雷达的干扰波形特征进行分析,提出了有效的处理措施以抑制雷达干扰波,从而保障解译人员能够有效、准确地识别雷达干扰波形,避免对雷达干扰波的误判。
Ground Penetrating Radar (GPR) has been used widely in tunnel engineering, however, interference factors are often encountered in the process of tunnel detection that lead to abnormal reflection waveforms covering the effective waveforms, which seriously affects the subsequent interpretation work. In this paper, the interference factors encountered in tunnelling detection are divided into three types, e.g., the coupling interference, construction interference and interference in special circumstances; the waveform characteristics of GPR interference waves are analyzed and effective treatment measures for inhibiting GPR interference factors are put forward, ensuring effective interpretation and identification of the interference waveforms and accurately avoiding the misjudgment of GPR interference waveforms.
