DYNAMIC PROPERTIES OF LIME AND LFA TREATED SOILS

This paper reports an experimental investigation of the dynamic properties of lime- and lime-fly ash treated soils. In treating weak clay soils and structurally unstable granular soils to support foundations subjected to earthquake or other forms of dyanmic loading, advantages of using soils treated with additives have not been fully utilized. The purpose of this investigation was to provide some of the needed information on the dynamic properties of some soils treated with additives. The dynamic properties in terms of dynamic shear modulus of and damping in two soils, a uniform sand and a silty clay, treated with lime-and lime-fly ash were determined by the resonant column technique. Test variables studied were treatment level (additive content), confining pressure, shear-strain amplitude and moisture content. These four variables were found to have the most profound effects on the dynamic properties. Static triaxial compression tests were also run on the same specimens to correlate dynamic properties with static strength values. A total of 88 specimens were analyzed. With various combinations of the test variables considered, a total of approximately 1,800 tests were performed. /Author/
