| Summary: | 碩士 === 國立臺灣科技大學 === 營建工程技術學系 === 84 === In this study,the infinite element is introduecd in the
existing three-dimensional finite element excavation program,
CUT3D, in which the required hard disk and computation time
are substantially reduced. Based on the parametric studies, it
is found that the good analysis results can be obtained if the
infinite element is placed at at a distance of one wall length
behind the wall. The analysis procedure is verified through two
case histories. The program is then used to analyze the Taipei
National Enterprise Center excavation project, which was
constructed with zoning. The field monitoring results for
ground movements for the Taipei National Enterprise Center
excavation project are also studied to understand the
characteristics of three-dimensional ground movements. Finally,
the plane strain ratio method is used to study the effects of
aspect ratio of the site and wall thickness on the wall
deformation.
