Popis: | 地盤や構造物は,微小変形領域では弾性的な挙動を示す.一方で液状化等を含む大変形領域では不連続体としての挙動が支配的となる.そこで,質点とそれを繋ぐ線要素から構成されるモデルに,ポアソン効果とせん断変形を考慮したばねを導入した離散要素モデルを開発し,微小変形から大変形・崩壊現象までを統一的に解析できる手法を提案する. The soil and structure shows an elastic property in the small displacement. On the other hand, the phenomena of the discrete particle system including liquefaction dominates the almost domain of the larger displacement. Therefore we take a new approach on the whole domain of deformation from an elastic continuity to discrete particles. It consists of corner springs for representing an effect of the Poisson’s ratio and shear deformation and straight elements, which are connected to concentrated masses. |
