摘　　要：提出一种新型的直流超前探测装置,即"U"形电极阵列超前探测装置,目的是提高直流超前探测的准确度,更好地消除或减弱非前方异常的影响。利用该装置在计算机上进行了数值模拟,并与传统的三点三极超前探测的效果进行了对比,之后又在实验室水槽中对该装置进行了物理实验。通过模拟结果以及一系列实验数据得知,该装置对探测前方的异常地质体有一定的效果。This paper proposes a new type of DC advanced detection device,which is named the ＂U＂-shaped DC advanced detection equipment,with the purpose of improving the accuracy of the DC advanced detection and better eliminating or weakening the impact of non-ahead geological faults.The authors used the computer to simulate the prospecting process by using the ＂U＂-shaped device and compared the result with that of the traditional DC advanced detecting device.The expected conclusions were reached.As the desired effect was obtained,the authors also carried out the flume experiments using the ＂U＂-shaped device.A series of experimental data and simulations have led the authors to believe that the ＂U＂-shaped DC advanced detection devices is efficient in detecting geological faults in a certain degree.
