探地雷达是利用超高频脉冲电磁波探测地下介质分布的一种地球物理勘探方法,由于其具有高效率、高分辨率、高准确率等特征,在浅层岩土工程勘察中应用越来越广泛.以国道G110改造工程勘察为例,介绍探地雷达在岩土工程勘察中的应用,对于确定断层的深部展布状况和花岗岩囊状风化界面起到了重要作用,给勘探孔之间地质体的推断解释提供了科学依据.%Ground penetrating radar is a kind of geophysical method which uses very high frequency pulse electromagnetic wave to explore the distribution of underground medium. It is widely used m shallow geotechnical investigation with high efficiency and high resolution Its effective is introduced by the project of G110 Road geotechnical engineering investigation It is exactly to locate the fault and weathered layer. The radar data is scientific evidence in interpret the complicated geotechnical phenomenon
