摘　　要：为研究秦巴山区公路隧道地质雷达波的识别标志,该文以安平高速公路隧道地质预报为依托,对所采集的地质雷达数据的波形、相位、振幅、频率和能量等标志进行了分析,探究了秦巴山区完整围岩、破碎带、富水带和洞穴四类地质条件下的地质雷达波识别标志特征,得到了岩体破碎程度、含水情况、洞穴与地质雷达波识别标志的关系。该文的分析结果为提高地质雷达超前预报的准确性和可靠性提供了一定的参考。In order to study the identification marks of ground penetrating radar wave in Qin-Ba mountain highway tunnels, in this paper, based on the geological predication reports of An-Ping highway tunnel, the collected marks of waveform, phase, amplitude, frequency and energy of the data of ground penetrat- ing radar are analysed. The identification marks characteristics of ground penetrating radar wave are dis- cussed under the four geological conditions of the integrated rock, fracture zone, water-rich zone and cave in Qin-Ba mountain area. The relationships between the rock fragmentation degree, water content, cave and the identification marks of the geological penetrating radar wave are obtained. The analysing results in this paper provide a certain reference for improving the accuracy and reliability of the advance forecast of geological radar.
