Abstract

Determining near-surface velocity structure is a crucial step in seismic data processing and imaging, especially in ENGINEERING SEISMOLOGY. First arrival SEISMIC TOMOGRAPHY can determine the velocity structure in area with strong lateral and vertical, velocity variations. SEISMIC TOMOGRAPHY has two major parts, forward modeling and inversion.Forward modeling generates ray paths and first arrival times in a prior VELOCITY MODEL and inversion updates the prior model to minimize data misfit. In this study a forward modeling' was carried out using a method based on finite difference and. LSQR algorithm to perform inversion. Velocity structure of the subsurface is represented by a grid model. A velocity value was assigned to each node within the grid, and velocity of a grid cell was determined by averaging of the velocities of the surrounding nodes.We applied the method for an engineering seismic project to explore velocity structure in near surface strata. The method was highly efficient and capable of recovering velocity structures in geologically complex areas. We also compared our results from tomography with that of the GRM method. It has been demonstrated that SEISMIC TOMOGRAPHY has more realistic results.
