Slope angles in friable loess
Maximum stable heights of steep, friable loess slopes of western Iowa and western Tennessee were found to relate to soil density and shear strength in accord with sliding-wedge method of analysis; shear strength was determined in situ with borehole shear test, which allows rapid field determination of Mohr-Coulomb failure envelope; observed geometry of steep slopes in friable loess is consistent with its in situ density and shear strength measured by borehole direct-shear test; observed average slope angles and sliding-wedge predictions suggest sequence of progressively flatter slope failures until angle of repose is reached.
