Engineering Properties, And Slope Stability And Settlement Analysis Related To Phosphate Mine Spoil Dumps In Southeastern Idaho, Richard Ellsworth Riker
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The engineering properties of waste spoil from phosphate mines in Southeastern Idaho were determined through field and laboratory testing. The testing included compaction tests, grain size analysis, powder x-ray defraction tests, permeability tests, compression tests, triaxial and direct shear strength tests, and nutrient analyses. Based on these tests, the slope stability and settlement characteristics of phosphate spoil dumps were investigated.
The study showed that the foundation is an important component of the stability of a spoil dump. Hypothetical examples were used to illustrate possible modes of foundation failures. Such failures might occur when weak foundation soils exist or when there …
