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.
