Abstract:: In order to explore the potential applications of the source of large-volume airgun to seismic-reflection detection of the structures of the continental crust,the test of airgun source excited by flowing water and received by seismometers for seismic reflection on the bank of the Yangtze River from Chizhou to Tongling in Anhui Provicne is conducted.The test is to obtain the profile of seismic reflection data below the survey line.The results show that the seismic waves excited by the source of large-volume airgun in the study area are characterized as long propagation distance and deep penetration.The clear first-arrival signal of seismic waves is obtained at the site 13 kilometers away from the shot point,and the continuous reflective layer could be distinguished at 10.5 s TWT,which is presumed to be the Moho interface.In data processing,the output line of the maximum coverage times is selected by comparative experiments.Finally,a clear stacking section is obtained.Due to the influence of observational systems and environmental noise,the test has some defects,such as low SNR of the large-range and deep signals,large divergence of common centerpoint,and lack of shallow coverage.However,the results of this experiment are sufficient to prove that,as a new artificial source,the airgun source can be used for seismic-reflection detection of the inland flowing water.
