In this paper, we introduce a novel direct time-domain artificial boundary condition, called
the scaled boundary perfectly matched layer, for wave problems in 3D unbounded fluid …

This work establishes a novel direct time-domain artificial boundary method for acoustic
wave problems. The proposed method, called scaled boundary perfectly matched layer …

The frequent occurrence of seismic activity in strong earthquake areas has led to the serious
damage of deeply buried underground engineering structures. In the face of numerous and …

The two-dimensional scattering and diffraction of plane SH waves by a symmetrical V-
shaped canyon with a circular underground structure in a half-space is studied by using the …

In this paper, the effects of two long unsupported parallel tunnels on the seismic response of
the ground surface are studied, using the boundary element method in the time-domain. The …

An analytical solution for the scattering of harmonic P1 and SV waves in a poroelastic half-
plane with a shallow lined tunnel is obtained using the plane complex theory in …

This paper presents for the first time the seismic analysis of a half-space containing a water-
filled valley under 2D oblique P-and SV-waves by the finite-infinite element (FE-IFE) method …

Better understanding the underground structure scattering on the wave propagation may aid
in the development of more safety earthquake resistant design and disaster prevention …

This paper presents a semi-analytical solution for the 3D problem of a cylindrical tunnel
embedded in an elastic half-space subject to plane harmonic compressional and shear …

Layered topographies and geologies are known to have considerable effects on the
spatially variable seismic motions scattered by a canyon in a layered half-space. In this …
