摘　　要：借线遥控电极阵列是一种新型供电—观测电极阵列,它借助常规电法勘探的供电导线和测量导线载波传送信号,遥控各导线与其链接的系列编码电极开关,从而有序地开展供电和测量。这种阵列的电极点距可灵活改变,供电电极间距可逐渐遥控扩大,实现了梯度测深阵列化测量。借线遥控器可以与单道电测仪、多测道电法仪、高密度电法仪等配合使用,组合后电极的阵列能更有效地开展二维/三维电法勘探。应用实例表明,与传统探测方式或高密度方式相比较,借线遥控电极及其组合阵列在矿产、岩溶等复杂地形地质条件下展现出高效率和高灵活性,拓展了电法勘探深部探测应用技术体系,具有推广价值和应用前景。The telecontrol electrode array is a new type of electrode array for power supply and observations that utilizes the carrier waves of the power-supply and measurement wires used in conventional electrical prospecting to transmit signals.By remotely controlling a series of coded electrode switches between various wires and their connections,this array allows for orderly power supply and measurements.This array enables flexible spacings between electrodes and the gradual expansion of the distances between power supply electrodes via remote control,thus achieving a gradient-based sounding array.The borrowing-line remote controller can be used combined with single-channel,multi-channel,and high-density resistivity instruments,and the combined arrays can perform 2D/3D electrical prospecting more effectively.Followed by the brief introduction of the principle of the borrowed-line telecontrol electrode array,this study discusses the applications and examples of this array and several combined arrays in the resistivity method and induced polarization(IP).
