| 摘 要： | 城市地铁工程中经常遇到岩溶等不良地质现象，勘察阶段需要查明其发育的位置及规模。然而，地下岩溶分布的隐蔽性、城市环境的复杂性使得岩溶勘察具有相当大的难度。本文采用综合物探方法对南京某地铁工程的岩溶发育情况进行了探查，分析以等值反磁通瞬变电磁法、弹性波CT法为主的综合物探方法在岩溶探测中的应用效果。

| Abstract: | The adverse geologic conditions such as Karst often threaten the safety of subway engineering. It is necessary to ascertain the location and scale of the Karst during the exploration stage. However, the randomness of Karst distribution and the complexity of urban environment make Karst exploration quite difficult. In this paper, we use the Opposing Coils TEM and Elastic Wave CT to prospect the Karst development of a subway project in Nanjing and analyze the application effect of comprehensive geophysical prospecting method which is based on opposing coils TEM and elastic wave CT method in Karst exploration. |
