Abstract
In order to test the performance of the LVIB-15 self-propelled light electro-hydraulic servo vibrator developed by Jilin University, a comparative test was conducted on different excitation conditions of a hard pavement and sandy road in Chaganhua town, Jilin Province, China. The optimum scanning frequency was determined by comparing different scanning frequencies. And seismic exploration with a length of 1.2 km was completed. The results show that the reflections were very clear and had good consistency. The signal-to-noise ratio of seismic signal was very high, reaching a reflector of 1400 ms, proving that the seismic data of vibroseis had high accuracy and reliable results and it meets the demand of geophysical prospecting.
