A STUDY ON A NEW MECHANICAL MODEL FOR FOUNDATIONS AND ITS ELASTIC SETTLEMENT RESPONSE

In the present paper, a new foundation model has been proposed by intr oducing a stretched rough elastic membrane in the Pasternak shear laye r sandwiched between two spring layers which is an extension of Kerr m odel. Considering the equilibrium of different elements, the equations governing the elastic settlement response of the model are derived. F inite difference scheme has been employed to solve the governing equat ions. The parametric studies carried out show the effect of several pa rameters on the elastic settlement response of the model. The proposed model is well suited for idealizing the behavior of geosynthetic-rein forced granular fill-soft soil system besides other applications.
