CERTAIN PROBLEMS OF THE COMPLEX MODULUS OF A FOUNDATION UNDER DYNAMIC LOADING

Abstract

The paper presents certain research results on determination of the complex elastic moduli of foundations consisting of loess, a sand base layer and fill. The effect of the base layer must be taken into account in determining the complex elastic moduli of a stratified foundation; approximate formulas are also proposed to allow for the area of the foundation and the effect of pressure; when a weak foundation is reinforced with a sand footing, there is a marked increase in its complex modulus. The complex modulus of a fill foundation is lower than that of the same type of earth in its natural state.
