【摘要】 高密度电法和音频大地电磁(EH4)测量技术是目前常用的地球物理探测技术,尤其对相对低阻地质体的探测具有较好的效果,且两种方法具有互补性和相互验证性。本文以灰岩地区探测溶蚀带、岩溶实践为例,探讨了利用物探方法寻找隐伏构造在工程勘察中所起的重要作用,实践表明基于电性参数的综合探测技术能够做到对地下溶蚀带、岩溶的定位预测,为水利工程后续的开展提供可靠的设计依据。更多还原

【Abstract】 Resistivity imaging and audio Geodetic electromagnetic(EH4) measurement technology are currently advanced and commonly used Geophysical detection techniques,which have a good effect on the detection of relatively low-resistance Geological bodies.The two methods are complementary and mutually validated.In this paper,the important role of geoscience exploration in the exploration of hidden structures is discussed.The practice shows that the comprehensive detection technology based on electrical parameters can predict the location of underground erosion zone and Karst,and provide a reliable design basis for the subsequent development of water Conservancy projects.更多还原
