This report presents the results of three separate but related projects researching questions on disposal of retorted oil shale. While motivated by oil shale problems the results are sufficiently fundamental and general to have application in other energy related applications. Research on liquid, vapor, and solute transport in relatively dry soils was completed with use of a dual source gamma ray system. The procedures used allow for the measurement of water and solute transport rates in unsaturated media down to near zero solution contents. Long-term stability aspects of waste disposal management developed for oil shale were extended for soils. The compressibility and water retention characteristics of a silty clay and a sand were measured. The stress-strain characteristics of spend oil shale, silty clay, and sand can be represented as a unique surface defined in terms of the void ratio, and the two stress state variables. Temperature and toe erosion effects on spent shale embankment stability were completed. High temperature triaxial cells were designed, manufactured and used to measure the stress-strain-strength properties of spent shales at elevated temperatures. The effects of toe erosion on embankment stability were determined by numerical modeling.
