Study of numerical simulation and application on well-ground seismic Tomography
井地地震CT成像数值模拟研究与应用

The principle of Well_Ground seismic CT determines that it has the advantages such as higher producing efficiency,lower producing cost and broader exploring areas.This paperfocuses on the well-ground geometry, the relative merits and application conditions between ART and SIRT,and suggests how to enhance the ray density, homogeneity and orthogonality by numerical simulations. Finally, the SIRT which has highest convergence rate is chosen for real work and a good result is obtained.So it proofs that the well-ground seismic CT has the correctness,feasibility and practicability.
