| Summary: | 碩士 === 國立成功大學 === 土木工程研究所 === 83 === A multi-region boundary element method (BEM) is developed for
the plane elasticity analysis in geo- mechanics including body
forces. The boundary element scheme considers the zoned
nonhomogeneous material property in the realistic soil media,
and the body force term in the scheme is transformed from
domain to boundary integrals. Uniqueness of solutions for
excavations in elastic media is demonstrated to be satisfied by
using the multi-region BEM where the lateral pressure at rest
is treated as calculated by using an appropriate coefficient
Ko. A geomechanics problem of footing founded on a horizontal
layer considering self weight is analyzed. The multi-region BEM
solution is compared with other available solutions in the
literature.
