Two-Dimensional Analysis of Ground Surface Displacements Using Pasternak Model

Classical Winkler Model has often been used f(〕r static soilstructure interaction analyses ． The model has some shortcomings because of the discontinuity of adjacent spring displacements ． Pastemak Model， as an improved soil model ， was applied 丘 )r the analysis of an elastic continuum on a rigid base in a plane strain condition ， The characteristics of Pasternak Model were evaluated by comparing the dispLacements of Pasternak Model with those of finite element analysis ， A simple explicit formulation of the ground su 漁 ce displacements was proposed in case of uniformly distributed vertical loads f｛)r practical use ， KeyWOtds ' Etastic anabsis ， Plane strav ' n ・ s・iX -stnvctwre irtteracti ・〃 ， Paster 〃ak M ・ det ， ( コ oefia ' ent Of subgratie reaction 弾
