摘　　要：为了解决传统直流电法隧道超前探测易受旁侧影响的问题,文章根据侧向测井的电极系布置,研究和提出了三种聚焦电流法隧道超前探测电极布置方式。在导电纸实验中,通过不同的电极排列方式和实验参数设置,研究和分析了聚焦电流法隧道超前探测效果的影响因素及其探测曲线特征。导电纸实验表明:聚焦电流法具有较好的超前探测效果,并且数据处理解释简单。In order to solve the problem that the traditional DC electrical advanced detection is disturbed by side anomalies, three electrode layouts are proposed and researched in this paper based on lateral logging. By testing the conductive paper, some effective factors and curve features of focused current advanced detection of tunnels are researched and analyzed by different electrode array and experimental parameters set . The results of the test shows that focused-current have a better advanced detecting effect with easier data process and interpretation.
