探地雷达是一种分辨率比较高的工程地球物理方法，对掌子面前方的溶洞、富水带、断层破碎带和裂隙带等不良地质现象有明显的异常反应。文中介绍了探地雷达在隧道超前预报中探测的原理、测线布置和数据采集方式，分析不良地质现象与围岩之间的结构和介电差异特征，设计合理的正演模型进行正演模拟，分析正演模拟图像的波形、频率、振幅、相位等特征，理论上总结了不良地质现象在雷达图像上的信号特征，并通过对实测典型雷达图像的解释，对不良地质现象的雷达反射波的频谱特征做进一步研究，可以为探地雷达在隧道超前预报中的解译提供参考。

Geology radar is a high?resolution engineering geophysical method which has abnormal reactions to karsts, water enriched zone, fault zones as well as the fractured zones and other geological phenomena in the front of the tunnel face. This paper discuss the principles of geological radar in advanced prediction, the layout method of surveying line and the data acquisition methods.The features of the structure and the permittivity difference between the adverse geological phenomena and wall rocks will also be discussed to design possible geological model to carry out forward modeling. The features of forward modeling such as the waveform, the frequency, as well as the amplitude is also the key point in this paper, and this paper summarizes the signal features of adverse geological phenomena in radar, theoretically and tries to do further researches on spectrum characteristic by analyzing the typical radar images , which will give clues to the development of the tunnel prediction.
