| 摘 要： | 灰岩地区岩溶普遍发育，所产生的溶蚀带、溶洞等不良地质现象，会严重地影响到高速公路路基工程质量与施工进度。高密度电法集电测深和电剖面装置于一体，由于它具有采集信息多，数据量大，观测精度高速度快和探测深度较大等特点，因而在工程地质和水文地质勘查中广泛应用。本文将高密度电法应用于云南某高速公路的岩溶勘察中，取得了很好的效果，为路基施工及岩溶的勘察治理提供了地球物理依据。

| Abstract: | With the wide development of the karsts in limestone region,the bad geological phenomenon such as the dissolution belt and karst cave bring a very bad effect to the engineering quality of the highway.Then the multi-electrode electric method which synthesizes electric sounding and electric cross section has been widely used in engineering and hydrologic geology prospecting,because of its characteristics of fast and large acquisition,high precision,and a great depth of detecting.In this paper,we apply this method in the karst exploration of a highway in Yunnan,and obtain good results.It provides the geophysical basis for the construction of roadbed and the reconnaissance and harnessing of karst. |
