| 摘 要： | 阐述了以综合物探为主要手段探测地下隐伏岩溶的工作原理及过程。针对岩溶勘探的特点，通过采用多种物探方法、布置高密度测网、勾绘高密度资料定性解释图性、剔除非可溶岩地层干扰影响以及总结一套简单实用的定性及准定量资料判释方法等５项措施，在南昆线岩溶复查工作中取得了良好的效果。

| Abstract: | The operating principle and process of detecting hidden underground karst with comprehensive geophysical prospecting method are stated.In accordance with the features of detecting karsts,five measures should be taken,including selecting various geophysical prospecting methods,arranging high-density survey grids,drawing high-density qualitative interpreting maps,rejecting disturbing affects of nonsoluable layers and using a set of simple practical principle about qualitative and quasi-quantitative discrimination.As these five measures were taken,the Karst checking in Nanning-Kunming railway was completed very well. |
