| Abstract: | This paper study simulates artificial surface seismic record of multiple-shot on the base of uniform-layer multi-medium model(as shown in Figure 10).The observation method is:three shot positions at 1 500 m,2 500 m,3 500 m;road distance 25 m,140 road(or road distance 5 m,700 road),offset 1 000 m.Combining the method ofP and S seismic wave's velocity tomography of minimum travel timewithP and S seismic waves velocity tomography of wave fundamental solutionto invert the interface shape and the velocity of P a... |
