unconfined aquifer correct answers The bottom flow boundary is defined by the aquiclude, but upper flow boundary (The groundwater table) is free to reach its own natural level. secondary consolidation correct answers Continuing settlement even after all pore pressures have dissipated Mohrs Circle correct answers Graphical representation of the relationship between normal stress and shear stress (transformation equations for plane stress) Quick Clay correct answers A water-saturated clay that changes to a fluid state when a heavy sudden force is applied 3 types of triaxial tests correct answers Unconsolidated-Undrained test, Consolidated-Drained test, Consolidated-Undrained test 3 lightweight fill materials correct answers shredded tires, geofoam, cementitious materials 3 components of total settlement correct answers Primary consolidation, secondary consolidation, settlement Define consolidation correct answers total pore pressure dissipation Difference between compact and consolidatioin correct answers Compaction is the densification of by application of mechanical energy. Consolidation is the natural way of pore pressure dissipating Define Compression Index (Cc) correct answers Slope of the virgin curve (did this in lab), represents a measure of the compressibility Define Recompression Index (Cr) correct answers Slope of the rebound curve, less sensitive to sample disturbance effects Two methods of calculating Coefficient of Consolidation (Cv) correct answers Casagrande's method and Taylor's method What does it mean to say that a soil is Overly Consolidated? correct answers There is a vertical stress on the soil that is greater than what the pre-consolidation stress was What does it mean to that a soil is Normally Consolidated? correct answers There is a vertical stress on the soil that is equal to what the pre-consolidation stress was Define Over Consolidation Ratio (OCR) correct answers A function that varies as a function of depth. Highest stress the soil ever faced. OCR=1 normally consolidated
