Summary: In this paper the concept of 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 W is formulated and solutions for several loading cases are worked out. Two material parameters enter the analysis: the viscosity parameter μ related to the shear deformations and ŋ 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.
