Geological disasters, active faults, special geotechnical bodies and ancient rivers are the main geological problems affecting the development of shallow underground space in cities, and nondestructive geophysical testing methods can be used for the detection of these geological problems. Tonghu ecological smart zone is an important area in the development of national ecological civilization construction demonstration zone and Huizhou smart city underground space. Shallow geophysical exploration and stratigraphic properties analysis provide detailed geological, geotechnical and geophysical data for the urban development and underground space utilization of the Tonghu ecological smart zone, which is an essential element for constructing the underground space model of the area. Although basic geological exploration research has been carried out for the region, comprehensive geophysical research on fine geological structures and stratigraphic divisions is still in the blank. In order to solve the problem of low level of fine detection in shallow underground space and limited resolution of traditional detection methods, the shallow reflection wave seismic method, S wave velocity structure imaging method of mixed source surface wave, three component resonance wave impedance ratio method and comprehensive logging method are used to perform highprecision stratigraphic division and fine interpretation of fault distribution for shallow underground space (200 m) in the area. Based on the shallow reflection wave seismic method to divide thick and largescale faults, the active source and passive source surface wave method are used to obtain more detailed shallow stratum and structural features, and the threecomponent seismic frequency resonance method is used to identify the shallow soil layer, which compensates for the low accuracy of the detection signal of a single method over different depth ranges. The response characteristics of stratigraphy and geophysics in the Tonghu area are discussed, and the detailed relationship between stratigraphic properties and geophysical parameters are constructed, which provides basic data for subsequent modeling.
