  • Ultimate and serviceability limit state reliability-based axial capacity of deep foundations

    Creator:
    Reddy, Seth C.
    Abstract:
    Deep foundations are necessary for the construction of many structures, such as bridges and buildings, located in areas unsuitable for shallow foundations. Owing to the inherent variability of soil and the complex changes that occur in the soil adjacent to deep foundations as they are installed, the ability to accurately...

  • GOSEP: Georeferenced Oregon Soil Engineering Properties

    Creator:
    Dutille, Victoria L.
    Abstract:
    Geotechnical engineers design and analyze the interface between the natural and built environments, often based on uncertain and inherently variable data due to the nature of the building material, soil. Engineers must estimate the subsurface conditions at a site using historical, in-situ, and laboratory testing data. However, only discrete representative...

  • Height Modernization from Static GPS Networks in Oregon: Evaluating NGS Guidelines and OPUS-Projects

    Creator:
    Kerr, Darren J.
    Abstract:
    Determining accurate elevations is important for many engineering and scientific applications, and finding these heights via GNSS increases efficiency and significantly reduces the costs as compared to precise geodetic leveling. The National Geodetic Survey (NGS) has published guidelines for determining both ellipsoidal and orthometric heights with GPS to within 2...

  • Evaluation of the Performance of Lateral Spread Displacement Empirical Models for Subduction Zone Earthquake Case Histories

    Creator:
    Bunn, Michael
    Abstract:
    Lateral spread is a pervasive type of liquefaction-induced ground failure that occurs on gentle slopes or near free-faces, such as river channels. Resulting horizontal displacements can reach up to several meters, and can be considerably damaging to foundations, bridges, roadways, pipelines, etc. In the 1990s, Bartlett and Youd (1992a, 1995)...

  • Tsunami and hurricane wave loads on bridge superstructures

    Creator:
    Azadbakht, Mohsen
    Abstract:
    This dissertation examines tsunami and hurricane wave loads on bridge superstructures. Tsunamis have caused significant damage to coastal communities in recent years. For example, the 2011 Great East Japan Earthquake and resulting Tohoku Tsunami destroyed infrastructure along the east coast of Japan including bridge superstructures. Recent hurricanes have also caused...

  • Small Unmanned Aircraft Systems (UAS) for Engineering Inspections and Geospatial Mapping

    Creator:
    Javadnejad, Farid
    Abstract:
    Small unmanned aircraft systems (UAS) carrying consumer-grade nonmetric cameras are increasingly utilized to generate high-resolution 3D geospatial data. Low cost, ease of operation, widespread availability and low altitude maneuvering capabilities of UAS, as well as the rapid development of technology and methods, make UAS-based photogrammetry applicable to many civil engineering...

  • Evaluation of Topography and Seismicity on Shallow Landslide Susceptibility

    Creator:
    Hess, Daniel M.
    Abstract:
    Shallow landslides are a prevalent concern in mountainous regions that can result in severe societal, economic, and environmental impacts. The challenge is further compounded as the size and location of a potential slide is often unknown. This study presents a generalized approach for the evaluation of shallow landslide susceptibility using...

  • Blast-induced liquefaction : observational estimation of vibration, settlement and residual pore water pressure

    Creator:
    Kato, Kengo
    Abstract:
    The blast technique has been used as an effective soil improvement method to compact loose coarse-granular soils since 1930s, and the use of the blast technique is extended as an application of in-situ liquefaction testing to investigate the performance of full scale foundations and countermeasures against liquefaction in recent decades....

  • Improving Interlayer Bond Quality with Engineered Tack Coats under Adverse Construction Conditions: A Laboratory and Field Investigation

    Creator:
    Wruck, Blaine M.
    Abstract:
    Tack coat emulsion, comprised of asphalt binder, water and emulsifying agents, is an interlayer membrane applied before asphalt pavement construction, which helps pavement layers bond together and permeate stresses and strains induced by heavy wheel loads through the entire thickness of the pavement structure. Proper interlayer bonding aids in preventing...

  • Soil-bridge interaction during long-duration earthquake motions

    Creator:
    Romney, Kyle T.
    Abstract:
    Earthquake engineering analyses are often performed using shallow, crustal earthquake motions (e.g., 1940 El Centro). However, large areas of the world are subject to subduction zone earthquake motions (e.g., the Pacific Northwest). A subduction zone earthquake motion is characterized by its long duration (e.g., strong shaking lasts for more than...
