| 摘 要： | 简要介绍了高频大地电磁法与地震折射波法的原理以及资料解释的特点,结合复杂的工程实例对同一测线两种方法的解释成果做系统的分析。由于高频大地电磁法(EH4)受外界干扰影响较大,无法对隐伏断层的低阻异常做出准确的判断,同样浅层地震折射波法不能对隐伏的断层破碎带做出合理的解释。通过两种方法的相互印证可以推断出隐伏断层的位置和走向。

| Abstract: | This paper introduced the principle of high--frequency electromagnetic and seis- mic refraction methods and the characteristics of data interpretation. With the complex en- gineering examples, it made a systematic analysis on the results from the two methods on the same surveying line. Because the high frequency electromagnetic method （EH4） is in- fluenced greatly by outside interference, the low resistivity anomalies of hidden faults can not be accurately judged and the shallow seismic refraction wave method can not provide a reasonable explanation for the hidden fault fracture zones. Comparing the two methods, the hidden fault location and trend can be deduced. |
