  • Engineering design and analysis of pipe ramming installations

    Creator:
    Meskele, Tadesse
    Abstract:
    The trenchless technology known as pipe ramming for construction of culverts and buried pipes under roadways or other infrastructure has gained significant popularity due to its cost-effectiveness and ability to alleviate surface disruptions associated with open-cut trenching. Although the experience with pipe ramming is increasing, there has been remarkably little...

  • Static and Wave Equation Analyses and Development of Region-specific Resistance Factors for Driven Piles

    Creator:
    Bougataya, Youssef
    Abstract:
    This study uses an existing database of dynamic loading tests of driven piles installed in the Puget Sound Lowlands to improve the reliability of axial performance. First, the unit shaft resistances developed from stress wave signal matching to dynamic records of pile installation are used to develop an effective stress-based...

  • 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...

  • Bearing capacity and immediate settlement of shallow foundations on clay

    Creator:
    Strahler, Andrew W.
    Abstract:
    Shallow foundations are extensively used to support structures of all sizes and derive their support from near surface soils. Thus, they are typically embedded up to a few meters into the soil profile. Designers of shallow foundations are required to meet two limit states: overall failure of the soil beneath...

  • Effects of soil slope on the lateral capacity of piles in cohesionless soils

    Creator:
    Barker, Paul D.
    Abstract:
    Deep foundations, including driven piles, are used to support vertical loads of structures and applied lateral forces. Many pile supported structures, including bridges, are subjected to large lateral loads in the form of wind, wave, seismic, and traffic impact loads. In many practical situations, structures subjected to lateral loading are...

  • Ground Improvement and Liquefaction Mitigation using Driven Timber Piles

    Creator:
    Gianella, Tygh N.
    Abstract:
    Seismically-induced liquefaction represents a major cause of damage to civil infrastructure and can result in significant damage following major earthquakes. Liquefaction can occur when earthquake ground motions raise pore-water pressures in loose, sandy soil, resulting in a substantial decrease of soil strength. Owing to the potential for instability following liquefaction,...
