| Summary: | 碩士 === 國立中央大學 === 土木工程學系 === 85 === The method of quicklime pile can improve the strength of the
soil groundeffectively. Most of the existing studies of the
consolidation mechanism inducedby the quicklime pile empoly the
experimental approach to study the consolidationby a group of
quicklime piles. Even though experimental data is the base of
the understanding of mechanisminduced by quicklime pile, we
still need to employ the numerical simulation.Thisis because the
numerical approach is more efficient and economical when we
studythe effects of variations of the geometrical and the
material parameters. In the existing literatures it is
thought that the radius of the regioninfluenced by a quicklime
pile is five times of the radius of the pile.In otherwords, the
distance between each two quicklime piles should be ten times of
thepile radius.However, our numerical simulations reveal that
this point should bere-examined. We also find that the radial
consolidation induced by the quicklime pile is indifferent to
the variation of the Young's modulus of the soil whileit is
affected significantly by the variation of the Poison's ratio.
