An Inverse Algorithm for Construction of Wave-Front Propagation and Evaluation of Rock Structures

摘要

In this paper, a numerical simulation for construction of the wave-front propagation and the related inverse procedure to identification of the velocity and/or material structures of rock mass, are proposed. The finite difference method and the finite element discrete technique are employed to modify the velocity structure and formulate the discretized raytracing field on the virtual finite elements. Both the slowness of the material and the amplitude of travelling waves are used as the inverse parameters in this study.
