  • 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...

  • Rigorous 3D Point Cloud Quality Assessment

    Creator:
    O'Banion, Matthew S.
    Abstract:
    The capabilities of modern three-dimensional (3D) capture technology such as laser scanning and image-based 3D reconstruction are well suited to enhance the practice and research of civil engineering. However, given the often-overwhelming focus placed on the incredible capabilities of these tools and techniques, it is important to investigate the limitations...

  • A Numerical Investigation of the Bearing Capacity of Shallow Foundations on Salt-Encrusted Flat Sabkha

    Creator:
    Refaei, Raied
    Abstract:
    Salt-encrusted flats, or Sabkha, are common in arid and semi-arid regions worldwide, including coastal and inland areas. Due to their low shear strength and high compressibility, these soils are often unsuitable for supporting infrastructure or structures. The unique salt content of sabkha formations sets them apart from other soil types....

  • Numerical Simulations and Microscale Analyses of Offshore Anchor-Granular Material Systems

    Creator:
    Zhang, Nan
    Abstract:
    Anchoring systems are used to hold floating offshore devices (e.g., energy devices, oil platforms) to keep them on their stations. Anchors are embedded into the seabed soils. In some cases, the interface shear between anchor and seabed soils together with anchor self-weight provide the holding capacity of the anchoring systems....

  • Unsaturated Soils and Foundation Design : Theoretical Considerations for an Effective Stress Framework

    Creator:
    Baker, Josiah D.
    Abstract:
    This study presents the theoretical background necessary to model the bearing capacity of shallow and deep foundations in partially saturated soils. The conventional bearing capacity equations for shallow and deep foundations and the 𝛽-method for deep foundation side resistance have been modified to include the effects of matric suction and...

  • Behavioral thresholds in mixtures of sand and clay

    Creator:
    Simpson, Daniel Corder
    Abstract:
    Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced (and in some cases, governed) by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

  • Engineering Behavior of Remolded Diatomaceous Silts

    Creator:
    Pitso, Talenta
    Abstract:
    Diatomaceous soils are a geological material whose engineering properties do not readily conform to the widely accepted and used mechanical and behavioral frameworks. This ambiguity results in design difficulties and geotechnical failures which can be costly. Diatomaceous soils have diatoms in their matrix. Diatoms are unicellular algae with an inert...

  • A New Bonding Model for the Particulate Simulation of Bio-Cemented Sand (with a Side Excursion on Percolation in Granular Mixtures)

    Creator:
    Khoubani, Ali
    Abstract:
    Bio-cementation is a promising method for the liquefiable mitigation of loose saturated sands. In the improvement process a bacterium that can be found naturally in soil deposits is fed urea. The bacterium consumes and breaks down the urea to form ammonium and carbonate. In the presence of calcium, calcium carbonate...

  • Seismic Performance of Square Reinforced Concrete Columns Retrofitted with Titanium Alloy Bars

    Creator:
    Lostra, Mackenzie M. W.
    Abstract:
    Large numbers of reinforced concrete (RC) bridges were built in the past that are now considered seismically deficient. The structural members most likely to be considered deficient are the supporting columns. Typical deficient columns contain inadequate transverse reinforcement and poorly detailed lap splice lengths above the foundation. Insufficient lap splice...

  • Bench-scale study for the bioremediation of chlorinated ethylenes at Point Mugu Naval Air Weapons Station, Point Mugu California, IRP Site 24

    Creator:
    Keeling, Matthew Thomas
    Abstract:
    Laboratory scale microcosm studies were conducted using site specific groundwater and aquifer solids to assess the feasibility of stimulating indigenous microorganisms in-situ to biologically transform Trichloroethylene (TCE) and its lesser chlorinated daughter products dichloroethylene (DCE) and vinyl chloride (VC). Three different treatments were conducted to determine the best approach for...
