| Abstract: | In this paper, a velocity depth model is constructed for layered media. Based on the model, a common reflecting segment based coherence inversion method for determining velocities and depths from seismic data is derived. Numerical modeling shows that the method is characterized by higher precision, better stability, and smaller error accumulated among layers. The results obtained by applying the method to the shallow reflection data from Songzikou of Jing River are comparable with the existing information, indicating that this method is promising. |
