  ABSTRACT: With the rapid development of the city, it is necessary to obtain geological information within 500 meters. Electrical prospecting is not only low cost and simple operation, but also solves the problem of insufficient drilling density in a survey. However, due to the dense urban buildings and strong electromagnetic interference, it is difficult for traditional electrical instruments to obtain effective data. An anti-interference electrical method instrument is designed. In the application test of Tongzhou core area in Beijing, the resistivity sounding data collected by anti-interference electrical method instrument is stable and reliable; inversion results of sounding are basically consistent with borehole data; the known Zhangjiawan fault and Yaoxinzhuang fault are obvious; basement karst collapse area inferred is basically coincident with the historical collapse area. It is proved that the anti-interference electrical method instrument is effective and can be applied to the geological survey of underground space in other cities.
