Abstract

In recent years, tunnels and underground engineering are developing rapidly, and meanwhile the topography, complex geological conditions making interpretation difficult in case of ground penetrating radar. To solve this problem, we introduce a two-dimensional forward simulation method for ground penetrating radar detection based on finite-difference time-domain method, which is proved to be effective through a numerical example: the position and shape of the adverse geological body can be inferred by analyzing the reflected signal from the finite-difference time-domain simulation results; and the relationship between the relative dielectric constants of the adverse geological body and the surrounding medium can be found by analyzing the phase information of the reflected signal.
