| 摘 要： | 花岗岩在我国有广阔的分布,对花岗岩的雷达波的研究可以为在花岗岩地区的工程建设施工提供有力的指导意义.通过对某隧道不同风化程度花岗岩进行地质雷达的测试,选取典型的雷达波进行频谱分析,探讨了不同风化程度花岗岩的地质雷达波的频谱特征.结果显示,全风化与强风化花岗岩的频谱能量均比较集中,但强风化花岗岩比全风化的花岗岩的频谱谱峰...

| Abstract: | The granite has vast distribution in China,the radar wave studies of granite provide effective guidance for the construction works in the Granite region.Based on the geology radar tests of granite with different weathering degree,and to select a typical radar wave spectrum analysis,this paper discusses the characteristics of radar wave spectrum of granite with different weathering degree.The results show that the spectral energy are more concentrated at the completely and highly weathered granites,the main frequency of the highly weathered granites is larger than that of completely weathered granites.The main frequency of the slightly weathered granites is not prominent,and the energy of radar wave is decentralized.The results provide a reference for analysing the weathering degree of granite by the ground penetrating radar. |
