Abstract:
Field surveys of the shallow refraction and microlog for both P-wave and S-wave have been made simultaneously in a work area. Rich field data and processing and interpretation results are obtained. In the paper, the field acquisition method and the final interpretation result are introduced emphatically.In the S-wave microlog survey, we flexibly solve some difficult woking problems and obtain desirable data. Also, SH-wave shallow refraction data with high S/N ratio are obtained. Based on the correlation of data derived from refraction and microlog for both P-wave and S-wave, we acquire the water table elevation in the work area by seismic method for the first time and draw some meaningful conclusions. P-wave and S-wave velocities, elevations, and layer thickness of the low velocity zone are derived.Finally, through the correlation of velocities extracted from microlog and weathering refraction shooting,the low velocity zone correction value for both P-wave and S-wave is given for the whole work area.
