摘要
岩溶溶蚀现象导致基岩面起伏较大,且溶洞发育严重影响了城市轨道交通建设的安全。以南京地铁工程为基础,采用高密度电法与地质雷达进行岩溶勘察,查明了该段岩溶分布范围、发育程度及形态特征。
The karst erosion results in a large fluctuation of the bedrock surface,and many karst caves seriously affect the safety of urban rail transit construction.Based on the Nanjing metro project,the karst geological survey on a certain section of Nanjing metro is conducted by using ground penetrating radar and high-density resistivity method.The distribution range,development degree and morphological characteristics of the karst area are identified.
