  • The evaluation of the field vane shear strength analysis of the Glen Aiken creek embankment failure

    Creator:
    Clarke, James Dennis
    Abstract:
    A post-failure investigation of a highway embankment constructed over organic and sensitive subsoils was made with a series of field vane tests. The results indicated that the embankment was quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...

  • Consolidation characteristics of sand-clay mixtures

    Creator:
    Anderson, Donald G. (Donald Gordon)
    Abstract:
    Combinations of cohesive and cohesionless soils are often encountered when evaluating the engineering properties of soils. The stress-volume characteristics of the mixed soil are found to vary according to the proportion of each component. If the cohesive soil composes more than a certain fraction of the material, the magnitude of...

  • Consolidation characteristics of calcareous deep sea-floor sediments from the Panama Basin

    Creator:
    Kao, Yeoung Ting
    Abstract:
    Calcareous sediments containing a large percentage of foraminiferal microskeletal tests were taken from sites in the Panama Basin and subjected to an investigation to determine the consolidation characteristics of this type of soil. The consolidation-stress curves and the time rate of consolidation curves in particular were investigated in this study....

  • An investigation of the feasibility of a cutbank slope design method based on the analysis of natural slopes

    Creator:
    Keener, Quentin Roosevelt
    Abstract:
    The failure of cutbanks is a major problem encountered by those who construct low-cost roads in naturally forested residual soils. Attempts have been made to lessen the severity of failures by classifying certain soil areas as to their susceptibility to failure, in addition to bringing past design experience into play...

  • Numerical method for calculating construction pore pressures in embankments

    Creator:
    Steward, John Erwin
    Abstract:
    A computer program was developed for estimating construction pore pressures in embankments without drainage at any location in the embankment at any time during construction. This program incorporated a modification of the Hilf-Brantz method of pore pressure calculation and a finite element method of stress computation. Previous methods of calculating...

  • Investigation of a nonwoven fabric as a reinforcement for gravel paved roads

    Creator:
    Kelsay, Harry Stanley
    Abstract:
    Full scale test roads combined with a theoretical analysis were used to evaluate the benefits of incorporating a fabric as a base course support material for gravel paved roads. One material, a synthetic, nonwoven, polypropylene fabric was used in this investigation. This fabric was used on top of the subgrade...

  • A model study of fabric reinforced earth walls

    Creator:
    Stilley, Alan Neal
    Abstract:
    The concept of placing high strength linear reinforcements in a soil backfill to produce a vertical retaining structure is a recent idea that has been applied with success at a number of locations. Rational procedures have been developed for the design of these structures when the reinforcements consist of long...

  • Ultimate bearing capacity of shallow footings on plastic silt

    Creator:
    Newton, Vernon C.
    Abstract:
    The usual approach to calculation of the ultimate bearing capacity of plastic silt is to assume no porewater drainage occurs during the loading period. The coefficient of permeability of plastic silt is generally significantly larger than clay; therefore, partial drainage of porewater may occur during the loading period. This study...

  • Fabric reinforcement of low embankments on soft foundations

    Creator:
    Greenway, Daryl Rodney
    Abstract:
    Nonlinear large deflection finite element analyses of a fabric reinforced embankment on muskeg were performed to predict fabric tension and the effect of fabric stiffness on embankment deflections. The predicted fabric tensions were compared with the results of a sliding block analysis, and show this simple analysis requires further correlation...

  • Fate of ammonia volatilized from a confinement livestock facility

    Creator:
    Hoffman, Eldon Randall
    Abstract:
    A conceptual model was developed to further the understanding of the evolution and fate of volatilized ammonia in the atmosphere. Recent trends in livestock rearing have been toward confinement facilities in which high animal concentrations are maintained. One of the impacts of these facilities has been increased local concentrations of...
