A hybrid boundary element method for computation of synthetic seismograms for a multilayered half-space: Theory of 2-D SH case
Boundary element method proves to be a useful method for investigating the seismic wave excitation and propagation in laterally inhomogeneous media which are often the case of the real earths crust. Such inhomogeneous medium is eligibly modeled as a stratified structure with irregular interfaces. For large-scaled models with many irregular interfaces, however, the computing time needed for the traditional boundary element method increases tremendously. Ge and Chen (2008) proposed a boundary element method combined with global reflection/transmission matrix propagators which is expected to solve this problem. In this paper, we show a detailed presentation of this promising approach by modeling a transient SH wave propagation, mainly including an easily-understood introduction to the method and some programming details, which is of great significance to those wishing to use boundary element method for the solution of engineering problems in seismological and geophysical fields.
