Abstract:This study makes full use of the surface wave and the primary wave information from the shallow reflection seismic data. We use the method of MASW to obtain the shallow shear wave velocity structure, and use first break travel-time tomography technology to obtain the P-wave velocity structure. Then, we get the velocity ratio and the poisson ratio data. Combined with the reflection wave stack section and the cross-fault borehole profile, the shallow strata are comprehensively interpreted. To some extent, our method compensates for the missing shallow reflection information, and plays a very important role for determining location and nature of the shallow faults.
