Abstract Three-component (3C) seismic technology to fine solve the near-surface geological problems has obvious advantages. Based on the point scattering seismic-geological model, we deduced multi-component scattering wave time-distance equation. On the basis of establishing the multi-component scattering wave imaging principle, we processed the 3C seismic data for the detecting city active fault in Jixian of Tianjin. Imaging results show that the wave group characteristics of the bedrock surface are obvious, insider structural features are rich, and minor faults near the bedrock surface are more development. Through this study, the contact relationship between the bedrock and Quaternary soil in the region is basic cleared, and the piedmont fault conditions and the geological structure of bedrock near the surface have been clear surveyed.
