- 摘要：Based on convection-diffusion theory, this paper established the two-dimensional model of radon migration in the finite depth soil cover above approximate vertical fault, derived the two-dimensional transient equations of the radon migration, and simulated the law of radon migration by using the staggered-grid finite-difference method. The influence of tectonic movement was added to the model to analyze the impact of seismic activity on surface radon concentration. When the depth of the soil cover is 50m, the effective diffusion coefficient is 2cm2/s, and the vertical convection velocity is
