  • Region-Specific Investigation of the Cone Penetration Test for Preliminary Classification and Estimation of Preconsolidation Stress, Undrained Shear Strength, and Cyclic Resistance of Transitional Silts

    Creator:
    Ortiz, Susan Christine
    Abstract:
    The Cone Penetration Test (CPT) has been widely-adopted for rapid, cost-effective exploration of the subsurface and reduction in the effort associated with drilling, sampling, and laboratory testing of soil. The adoption of the CPT has stemmed in part to the correlation of measurements to preliminary soil classification, stress history, drained...

  • An investigation into the role of spatial variability on liquefaction consequence severity

    Creator:
    Cary, John R.
    Abstract:
    During the Canterbury Earthquake Sequence (CES) in Christchurch, NZ, an estimated $15B in damages occurred due to liquefaction-induced phenomena, illustrating the importance of understanding site-specific responses to seismic ground motions, as well the importance of accurately predicting liquefaction severity. One potential method for improving the understanding of how a site...

  • Jet diffusion as related to ocean outfall systems

    Creator:
    Buford, Gary Manford
    Abstract:
    This study discusses important aspects of the ocean which should be considered in the design of a sewage outfall system; conditions are restricted to those of the Oregon coastal area. They include predominant currents, upwelling tendencies and ocean bottom characteristics. Major emphasis is placed upon investigation of diffusion characteristics of...

  • 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,...

  • A Full-Scale Experimental Investigation of the Bearing Performance of Aggregate Pier-Supported Shallow Foundations

    Creator:
    Martin, John P.
    Abstract:
    Aggregate piers have been used for centuries, with increasing occurrence in the last few decades. Their usage has been driven by land development demand and enabled through equipment and engineering improvements. Understanding the principles controlling bearing capacities and serviceability performance has been an ongoing area of interest for structures supported...

  • Flow slide control with slope revetments

    Creator:
    Narkiewicz, Steven Arthur
    Abstract:
    This paper examines the response of submerged model sand slopes to vibration and the beneficial effects of placing rock revetments on the face of the slope to prevent flaw slides. Pore water pressure response and deflection were used as a criteria for stability in an attempt to relate stability with...

  • Use of Controlled Blasting to Quantify the Dynamic, In-Situ, Nonlinear Inelastic Response of Soils

    Creator:
    Jana, Amalesh
    Abstract:
    The seismic response of deep deposits of liquefiable and cyclic-softening susceptible soils has presented the geotechnical profession with significant engineering challenges. Strong ground motions may serve to soften soils under cyclic shear, trigger liquefaction, and produce damaging displacements as a consequence. This study improves the understanding of the in-situ, nonlinear,...

  • 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...

  • Vibration induced pore pressure development in graded sands

    Creator:
    Steinkamp, Henry Vincent
    Abstract:
    During construction of the embankment at Blue River Dam placement difficulties were occasionally experienced with the filter zone sands. In the extreme condition construction equipment became mired and part of the fill had to be removed and wasted. A laboratory investigation was conducted on materials from the above project to...

  • Economic comparisons of different highway networks in a given region

    Creator:
    Ergün, Tevfik
    Abstract:
    This thesis presents an economic comparison of three different highway networks which serve an area of 64 miles by 83 miles in size. Each network is designed to carry the same traffic between any two towns but is different in total length. Costs of right of way, excavation, pavement and...
