同高密度电法相比，并行电法系统采用拟地震式数据采集方式，其勘探效率和数据采集量大大提升，利于对目标体的辨识。通过构建覆盖层隐伏洞体模型，采用有限元法对比分析不同装置下的电性断面特征，模拟结果显示温纳偶极装置对覆盖性洞体探查具有较强的分辨能力。现场隧洞探查应用结果也表明，温纳偶极装置的视电阻率和反演断面均与洞体实际情况吻合，并行电法对隐伏性异常体勘探实用性强。

Compared with the high density resistivity method,parallel electrical imaging method has greatly im-proved exploration efficiency and been beneficial to target identification due to the Pesudo -seismic data acquisi-tion mode.A hidden cave model with resistivity is built using FEMmethod to compare and analyze the various ar-ray features of 2D inversion section.The results show that Wenner βarray detects covered -caves efficiently.An engineering case is then given by using the parallel electrical imaging system to find the rocky tunnel.Application results demonstrate that the apparent resistivity and the inversion profile by using Wenner βarray match the actu-al situation,which shows the high accuracy of parallel electrical method in covered -caves exploration.
