摘　　要：在对滑坡、地面塌陷等典型黄土公路地质缺陷完成一系列探测试验的基础上,重点开展了穿越211国道陕西泾阳地震台地裂缝的综合探测研究,投入了纵波及转换波反射地震、多道瞬态面波地震、高密度电阻率法、瞬变电磁法等多装置、多参数综合近地表地球物理探测方法。利用高阶面波参数提取、多波层析成像、电阻率模拟反演等技术,获得了与工程实际吻合的地裂缝病害探测结果,为该地区公路工程的防灾减灾及安全运营提供了参考资料。On the basis of detecting and testing the typical defects under loess highway such as landslide and surface collapse, we carried out integrated geophysical detection on the ground fissure beside Jingyang seismostation in Shaanxi national highway 211. The near surface geophysical methods with multi--devices and multiple parameters, such as, PP and PSV reflection seismics, multi--channel transient surface wave method, high--density e- lectrical method, and transient electromagnetic method, are adopted in this test. Multiple --mode surface wave parameter extraction, multi--wave tomography and electrical resistiv- ity inversion techniques are researched respectively. And the results achieved of the ground fissure are in agreement with the practical situation. The achievements of this research can be used as a reference in disaster prevention and safe operation of the highway in this area.
