SETTLEMENT AND TILTING OF FOOTINGS ON A VISCOUS FOUNDATION

Abstract

IN THIS PAPER THEONCEPTOF THE Pasternak foundation, consisting of the Winkler foundation with shear interactions, is extended to the case of viscous behavior. The differential equation for the vertical surface displacements is formulated and solutions for several loading cases are worked out. Two material parameters enter the analysis: the viscosity parameter related to the shear deformations and a visco-compressibility parameter of the vertical foundation elements. A procedure to determine these parameters is suggested. The application of this analysis to the creep behavior of snow foundations is discussed. (Author)
