摘要
在岩溶分布地区易发生地面塌陷等地质灾害,物探是隐伏型岩溶地质调查的一种重要手段。高密度电法是一种快速、高效、经济的浅表岩溶构造勘察手段,通过在向家坝至上海±800kV特高压直流输电线路工程中的应用,介绍了该法能提供浅表截然不同的地电层的界限,能显示岩溶地区土壤和岩性的变化,特别是能有效地探测破坏性的岩溶构造。
In karst distribution areas,the geological disasters occur easily,so high-density electrical method is a rapid,efficient and economical means for detecting shallow karst structure. Applying the Xiangjiaba ~ Shanghai DC 800kV UHV power transmission line engineering,this paper introduces the boundary of different geoelectrical layers,which can show the changes in soil and lithology of the karst areas and especially can detect those damaged karst structures.
