パステルナーク・モデルを用いた剛基盤上の3次元弾性地盤における軸対称静的地表面変位解析

抄録

Classical Winkler Model has often been used for static soil-structure interaction analyses. The model has some shortcomings because of the discontinuity of adjacent spring displacements. Pasternak Model was proposed as an improved soil model and applied for the static analysis of an elastic continuum on a rigid base in an axisymmetric condition. The characteristics of Pasternak Model were evaluated by comparing the displacements of Pasternak Model with those of the finite element analysis. The ground surface displacements were explicitly formulated in case of uniformly distributed vertical circular loads for practical use.
