We analyze the problem of a heterogeneous formulation of the equation of motion and
propose a new 3D fourth-order staggered-grid finite-difference (FD) scheme for modeling …

An extensive investigation has been made into the interaction between topographic
amplification and soil layer amplification of seismic ground motion. This interaction is …

Recent researches have revealed that the seismic ground response above tunnels can be
different from the free-field motion during earthquakes. Nevertheless, to the best of the …

高山峡谷复杂地形是我国西部地区常见的地形和场地条件, 大量的工程(桥梁, 大坝等)

In this paper, a half-plane time-domain boundary element method (BEM) was presented for
analysing the 2-D scalar wave problems in a homogenous isotropic linear elastic medium …

A direct half-plane time-domain boundary element method (BEM) was developed and
successfully applied to analyze the transient response of ground surface in the presence of …

Buildings located on hill slopes are subjected to additional effects under seismic action
compared with those on flat ground. This article presents Incremental Dynamic Analyses of …

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 …

Following the success of seismic analysis of a canyon [1], the problem of SH-wave diffraction
by a semi-circular hill is revisited using the null-field boundary integral equation method …

In this paper, the method of combining indirect boundary element method (IBEM) with the
region-matching technique is used to solve the seismic responses of a three-dimensional …
