该文以相同工区、相同测线上采用高密度电阻率法和地震折射波法相结合进行勘探为例,对划分地层界面,确定覆盖层厚度进行了综合对比与解释,结果表明:折射波法弥补了高密度电法分层的不足,而高密度电法弥补了折射波法对层面周围环境无法得知更详细地质情况的缺陷。当地球物理条件较差时,地震折射波法比高密度电法的勘探效果好。如果这两种物探方法相互补充,可得到更准确的地质构造。
Taking the exploration of the same work area and the same survey line by using the method of high-density resistivity and seismic refraction wave method, this paper makes a comprehensive comparison and interpretation of the stratigraphic interface and the determination of the cover thickness. The results show that the refraction wave method can make up However, the high-density electrical method compensates for the defect that the refraction wave method can not know more detailed geological conditions of the surrounding environment. When the geophysical conditions are poor, the seismic refraction wave method is better than the high-density electrical method. If these two geophysical methods complement each other, a more accurate geological structure can be obtained.
