地质雷达作为隧道超前地质预报的重要方法之一,在隧道施工中已经得到了广泛的应用。该文针对回波信号的特点,提出了一套完整有效的雷达数据处理流程,并基于时域有限差分方法对基本地质体回波波形特征进行了研究,从而建立了雷达超前地质预报回波图像的解译流程和方法。实践证明,该文提出的方法可以有效地保障雷达超前地质预报数据的处理效果和解译精度,对于地质雷达在隧道超前地质预报工作中的应用具有重要意义。
As one of the most important geological prediction methods of tunnel, geological radar has been widely used in tunnel construction. In this paper, a set of complete and effective radar data processing flow is proposed according to the characteristics of echo signals. Based on the finite difference time domain method, the characteristics of the echo waveform of the basic geologic body are studied, and the radar advanced geologic prediction echo image The interpreter flow and method. Practice has proved that the method proposed in this paper can effectively guarantee the processing effect and interpretation accuracy of the advanced geological prediction data of the radar and is of great significance to the application of the geological radar in the advanced geological prediction of the tunnel.
