| 中文摘要: |
| 灰岩区的溶蚀现象不仅会导致基岩面起伏很大，还会产生溶蚀带、溶洞、土洞等地质现象，严重影响到该地区工程建设。近年来，根据溶洞、土洞与其围岩电性的差异，使用电法勘探寻找溶洞、土洞取得了较好的效果。单极-偶极时间域激电测深方法在建筑场地岩溶勘查中的应用表明，该方法对于查明建筑场地岩溶、土洞的存在以及分布范围是一种有效的地球物理勘探方法。 |
| 英文摘要: |
| Dissolution of limestone dose not only lead to tremendous undulation of the bed rock surface but also the bad engineering geological phenomenon, such as dissolution zone, karst and soil caves that would influence construction of many projects. According to difference of electric property between the dissolution zone, karst and soil caves and their surrounding rocks Pole-Dipole high power IP method has been applied to detection of them and good result achieved in recent years. |
