摘　　要：在交通线路设计勘察中,查明隧道段覆盖层的厚度、隧道洞身位置地震纵波波速度、断裂构造等不良地质体的分布,是隧道工程物探勘察的主要地质任务。物探方法中的地震折射法、高密度电法,大地电磁测深法(EH-4)等是隧道工程物探中常用而有效的物探方法。本文介绍地震折射法与高密度电法、大地电磁测深法(EH-4)相结合的综合物探方法在隧道勘察中的应用效果。In the design and survey of traffic routes,it is the main geological task of tunnel engineering geophysical exploration to find out the thickness of the tunnel section,the seismic longitudinal wave velocity of the tunnel body and the distribution of unfavorable geological bodies.The seismic refraction method,high-density electric method and magnetotelluric sounding method(EH-4)in geophysical methods are commonly used and effective geophysical methods in tunnel engineering geophysical exploration.This paper introduces the application effect of integrated geophysical methods combined with seismic refraction and high-density electrical method and magnetotelluric sounding method(EH-4)in tunnel survey.
