Abstract: Geophysics has become an important technical precaution in the detection of urban underground space. The urban
underground space is located under the ground. Before the construction, the unknown underground space and the changeable
geological conditions need to be identified by various means, among which geophysical exploration is the most convenient and
effective detection method in the early stage. On the basis of geophysical exploration results, the development law of adverse
geological processes can be preliminarily determined, which provides the basis and reference for the next specific exploration
program. Thus, the efficiency of exploration is improved, the cost of exploration is saved, and the working effect is improved. This
paper described the use of apparent resistivity high-density method and shallow geological radar method to explore a new city
construction site to 50 m underground shallow strata distribution, identify the fault structure, and divide the interface between the
overlying clay and the entire weathered layer and the underlying bedrock. After that, the abnormal area of geophysical prospecting
was verified by drilling, the results of geophysical exploration were further compared and analyzed, and the laws of formation
electrical characteristics were summarized, which provided a reliable basis for the formulation of the next exploration program.
