  • Scourability of weak rock in the Oregon Coast Range

    Creator:
    Baillie, Michael W.
    Abstract:
    The undermining of bridge foundations can lead to either costly repairs or a bridge collapse. These foundations must be designed to counter the effects of scour. Current practice does not allow for accurate estimates of scour in erodible rock. Scour in rock can be related to geotechnical and hydraulic properties....

  • Land surface energy balance and surface soil moisture variation in HAPEX-MOBILHY

    Creator:
    Nichols, William E.
    Abstract:
    The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the...

  • The seismic vulnerability of sheet pile walls

    Creator:
    McCullough, Nason J.
    Abstract:
    The seismic performance of port structures has been well documented following recent earthquakes, and indicates that port structures are highly susceptible to earthquake-induced damages. These damages are primarily due to soil liquefaction and the associated ground failures. Sheet pile bulkheads provide vital intermodal and lifeline transportation links between water-side and...

  • A determination of ultimate pile capacity in clayey silt

    Creator:
    Thompson, Duane Melvin
    Abstract:
    Predetermining the ultimate capacity of piles driven into purely cohesive soils and purely cohesionless soils involves, respectively, the consideration of soil shear strength in a completely undrained and a completely drained condition. For the intermediate cases concerning soils that possess both cohesion and internal friction (silts, clayey silts, sandy clays,...

  • Frequency and magnitude of bedload transport downstream of the Pelton-Round Butte Dam Complex, lower Deschutes River, Oregon

    Creator:
    Fassnacht, Heidi
    Abstract:
    A first-order approximation is made of the frequency and magnitude of bedload transport downstream of the Pelton-Round Butte Dam Complex, lower Deschutes River, Oregon with implications for salmonid spawning habitat. Field measurements of channel hydraulics, geometry, and particle size were combined with one-dimensional hydraulic and bedload transport models to determine...

  • 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....

  • Pile hammer selection by driving stress analysis

    Creator:
    Barrero-Quiroga, Franklin
    Abstract:
    This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...

  • Engineering properties of Southeast Alaskan forest soils

    Creator:
    Filz, George
    Abstract:
    The strength of both undisturbed and compacted soils from 10 sites in the slide-prone Tongass National Forest in SE Alaska were studied. Index property tests were also conducted on disturbed samples. The index tests included natural water content, Atterberg Limits, specific gravity of solids, grain size distribution, and moisture-density relationship....

  • 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...
