摘要
在黄土洞穴探测中经常用到的是电法勘察,其中常用的是对称四极电测深法,这种方法要求施工场地较大,有足够大的布极空间。本次施工地区位于高速路桥底,施工场地受限。针对上述情况,本文主要介绍了三级电测深法在黄土洞穴探测中的应用,并对这种方法的原理、工作方法、资料处理和资料解释进行分析。最后通过实例得出三极电测深法在黄土洞穴探测中能取得较好的效果。
Electrical prospecting methods are often used in loess cave detection.Among them,the commonly used is a symmetric quadrupole electrical sounding method,which requires a bigger construction site.The construction area is located under the bridge of the highway,so the site is limited.In view of the above situation,this paper mainly introduced the application of the tri-electrode sounding method to loess cave detection,then analyzed its principle,working method,data processing and data interpretation,and finally obtained a good result from the application of tri-electrode sounding method to loess cave detection.
