The multi-wave and multi-component seismic exploration method has been widely used in oil and gas field exploration and development. While this method has not been applied to engineering surveys and active fault investigations. This paper introduces briefly the data acquisition and processing methods applied to the three-component shallow seismic reflection test as well as some primary results on the Huangzhuang-Gaoliying fault in Beijing. The results show that using the shallow seismic data-acquisition technology with P-wave or S-wave vibroseis and three-component geophone, the shallow seismic P-wave, S-wave and converted-wave stacked section with high signal-noise ratio could be obtained. Especially the converted-wave and shear wave from horizontal components can reveal meaningful underground structure and tectonic information. Integrated geological interpretations of P-wave, S-wave and converted-wave staked sections yield stratification and fault structure which are consistent with the composite cross section from borehole data.
