Effects of Oblique Incidence of SV Waves on Nonlinear Seismic Response of a Lined Arched Tunnel
The incident direction of earthquake motion is an important factor affecting the seismic response of underground structures. In this study, a three-dimensional (3D) oblique incidence method of SV waves is proposed and the effects of incident angles of SV

Tube waves, seismic waves and effective sources [PDF]
The radiation of waves from a monopole source in a fluid-filled borehole into an elastic medium is considered. A simple asymptotic analysis, based on the smallness of the ratio of the borehole radius to the wavelength, reveals the interaction between tube waves and seismic waves.
