探地雷达作为公路隧道超前地质预报的手段之一,对预报掌子面前方岩体的微细结构能起到很重要的作用,同时可以作为隧道勘察结果的进一步认识和补充.以新扎沟隧道为例,利用SIR-20探地雷达并结合工程地质方法,对节理破碎带和地下水成功地做出了预测.对这几种不良地质体雷达反射波的频谱特征做了简要研究,为以后探地雷达探测数据的解译积累了经验.

As an instrument of advanced geological forecast method in road tunnel, GPR(Ground Penetrating Radar)plays an important role to predict remote structure in the front of facing frontage and can be the further realization and supplement of tunnel prospect at the same time.On the basis of simply introducing the principle of electromagnetic wave of GPR in paper, it is successful to forecast the the faulted zone and ground water which exist in Xinzhagou tunnel using SIR-20 GPR and engineering geology technique. The paper simply make a research on the characteristics of frequency spectra of GPR' reflective wave to these harmful geological bodies and it will contribute to interpret the future detecting data.
