Abstract: Concrete dam-foundation dynamic interaction plays an important role in the earthquake response analysis and safety assessment of the high concrete dam. Based on perfectly matched layer（PML） theory, the wave equation and finite element equation of perfectly matched layer artificial boundary in time domain are deduced and implemented. The accuracy and stability of PML artificial boundary simulation of far-field radiation damping is verified through the problem of wave absorption under the transien... More
