摘　　要：该文将电阻率成像法应用到城市工程中,经过预处理和滤波等数据处理手段,剔除干扰数据;利用FlashRES64多通道电阻率剖面直流电法勘探系统采集数据量大的特点,反演时尽量精细划分反演剖分单元,提高成像结果的分辨率;解释时与实际工程相结合,有效解决了天津市某路面坍塌及人防通道探测,取得了较好的效果。In this paper,the resistivity imaging method is applied to urban engineering. The interference data is eliminated by preprocessing and filtering. The FlashRES64 multi channel resistivity profile directcurrent electrical prospecting system has the characteristic of prospecting a large number of data,through the inversion,the inversion section unit is divided finely as far as possible,and the resolution of imaging result is improved; The interpretation is contacted with the actual engineering,and it is effectively to solve a pavement collapse and the civil air defence passage detection in Tianjin City,and it gets good effect.
