摘　　要：应用高密度电阻率法勘探对太原市晋源区某场地进行评价,借助电性参数,得到了东西分段上下分层的沉积展布特点。进一步认识清楚了山前冲洪积扇的规模和特点,最浅处为24m,最深处为36m;找到了潜水界面,定性判断出潜水面水位,且有东浅,西深的特点。结合遗迹物质成分分析,验证了护城河有低电阻率,古城墙地基基础成高电阻率的特点。通过高密度电阻率法勘探,取得了丰富的地球物理特征认识,为后续有效利用该场地提供了地球物理特征信息。In this paper, we have applied high density resistivity on the site evaluation to some place in Jinyuan, Taiyuan. Acoording to the electric parameters, we have got the character of the sediment distribution that the east section and the west section are layered differently, knew the extent and charater of the mountain front alluvial proluvial fan further, the shallowest of which is 24m and the deepest of which is 36m, found the ground water inerface, and characterized the ground water level that is shallow in the east and deep in the west. We have verified that the moat is of low-resistivity and the ancient city wall is of high-resistivity combined with the analysis of antiquity materials. By the work in this article, we have got a lot of geophysical information for further application of the site.
