摘　　要：介绍了浅层地震折射波法及高密度电法基本原理和方法,结合工程勘察实例,阐明折射波法和高密度电法在铁路、高速公路隧道勘察中的应用效果,并介绍了这2种方法相结合在查明隧道隐伏构造和破碎带等不良地质体的位置、规模、性质、特征中的应用效果,提出提高这2种方法勘察精度的几个举措。Basic principles and techniques for the shallow seismic refraction wave method and the high-density resistivity method are described in this paper in combination with engineering practice to explain the results of the refraction wave method and the high - density resistivity method in railroad and highway tunnel exploration. The application effects of the combination of these two methods in detecting positions, sizes, natures and characteristics of such harmful geological bodies as concealed faults and shatter zones are also discussed. Some measures for improving the investigation accuracy of these two methods are put forward.
