摘　　要：韩城市位于祁吕贺山字形构造的前弧东翼与新华夏构造体系第三沉降带的复合部位。以东北–西南向的山前大断裂(即韩城大断层)为界,东南面属渭汾地堑,西北面属鄂尔多斯台向斜的陕北盆缘褶皱区,开展地表基质层研究具有重要意义。综合地球物理探测是开展近地表无损探测的重要途径。利用天然源面波法和高密度电法综合物探方法,对陕西韩城地区地表基质层进行垂向分层,取得了较好的效果。Hancheng City is located in the composite area of the eastern wing of the front arc of the Qiluhe Mountain shaped structure and the third subsidence zone of the New Huaxia tectonic system. It is of great significance to conduct research on the ground substrate layer, with the northeast southwest direction of the Shanqian Fault (i.e. the Hancheng Fault) as the boundary. The southeast belongs to the Weifen Graben, and the northwest belongs to the folded area of the northern Shaanxi Basin in the Ordos Platform Syncline. Comprehensive geophysical method is an important way to carry out non-destructive detection near the surface. The vertical stratification of the surface matrix layer in the Hancheng area of Shaanxi Province was achieved using a combination of natural source surface wave and high density resistivity method, and good results were achieved.
