高密度电法具有经济高效、信息量大、抗干扰能力较强等特点,结合高密度电法在云南昆明西北三环高速公路大长隧道勘察中的应用,对高密度电法的工作布置、装置选择、资料处理等方面进行分析和研究,表明在合适的地球物理背景下,高密度电法能较好地反映隧道所经区域的岩性特征及不良地质情况的分布,并通过钻孔验证了推断成果,为隧道进一步的勘察设计提供可靠的依据。结果表明高密度电法作为一种经济快速的勘探方法在高速公路大长隧道勘察中具有较好的效果。
The high-density electrical method has the characteristics of high efficiency, large amount of information and strong anti-interference ability. Combining with the application of high-density electrical method in the investigation of the Dachang tunnel of the 3rd Ring Expressway in Kunming, Yunnan Province, Device selection, data processing and other aspects of analysis and research shows that under the appropriate geophysical background, high-density electrical method can better reflect the tunnel through the lithology characteristics of the region and the distribution of adverse geological conditions and verified by drilling Inferred results, for the tunnel further investigation and design provide a reliable basis. The results show that high-density electric method has good effect as an economical and rapid exploration method in Dachang tunnel exploration of expressway.
