摘要
该文介绍了在昆明市开发区某拟建公路勘察中,利用高密度电法探测覆盖层、岩溶、断层等不良地质体,查明了覆盖层厚度及基岩埋深,表明测区无土洞和岩溶发育。经钻孔验证物探推测结果与钻探成果较为吻合,验证了高密度电法的可靠性。
This paper introduces the unfavorable geological bodies such as overburden,karst and faults are detected by using high-density electrical method during the survey of a proposed road in the development zone of Kunming City.The thickness of the covering layer and the buried depth of the bedrock have been found out and there are no soil caves and karst development in the surveyed area.The geophysical prospecting results verified by drlling are in good agreement with the drilling results,which verifies the reliability of the high-density electrical method.
