摘 要:对于高速公路、桥梁、大坝等高标准工程项目建设,为了便于选址,须确定地下有无溶洞及其有关参数.作者在获得可靠地质信息的基础上,利用电测深法对宁横公路某路段地下溶洞进行探测,并利用反射系数(K)法对其ρs资料进行解释.结果表明,用电测深法探测岩溶,能较准确地确定溶洞的规模及其空间赋存状态,具有广阔的应用前景
Abstract: In order to chose the position of high standard projects such as highways, bridges and embankments, it is necessary to determine the exising krast and its relative parameters. On the basis of obtained reliable geological information, the authors use the resistivity sounding method to survey a section ofNing-Heng highway, and explain itsρsinformation using reflection cofficient (K) method. The results show that the resistivity sounding method can exactly reflect the karst and determine its scale and space position, and so it has great prospects in this field.
