  • Sustainable Design Programs in the United States and Chile

    Creator:
    D'Acci, Hana
    Abstract:
    The purpose of this thesis is to examine and compare sustainable design methods used in the United States and Chile, focusing on sustainable materials and certification programs, to see if sustainable design methods used in the United States can be implemented in Chile to further its sustainable development. Through literature...

  • 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...

  • Tsunami-induced Soil Instability

    Creator:
    Fischer, Rachael Marie
    Abstract:
    Recent tsunami field surveys from the 2011 Great East Japan Earthquake and Tsunami have recorded numerous examples of tsunami-induced soil instability: significant scour around foundations, foundation failure of piles, and other damage caused by liquefaction. From the observations of soil instability leading to the failure of critical coastal structures, it...

  • Influence of expansive soils on structures in the Eugene area

    Creator:
    Bonell, John Alexander
    Abstract:
    Expansive soils in Eugene, Oregon present a problem to residents, consultants, contractors, and the city government. During the years 1977 to 1979, the nature and extent of the problem was identified, including an outline of the local occurrence of expansive soils and possible engineering solutions to the most often encountered...

  • Hydraulic functions of soils from physical experiments and their applications

    Creator:
    Su, Charles
    Abstract:
    Based upon the Pearson Type VIII distribution function, a general retention function which relates the saturation to the capillary pressure in disturbed soils has been discovered. This simple and yet complete function has been shown to describe precisely the imbibition as well as the drainage branch of the retention curve....

  • Fabric reinforcement of low embankments on soft foundations

    Creator:
    Greenway, Daryl Rodney
    Abstract:
    Nonlinear large deflection finite element analyses of a fabric reinforced embankment on muskeg were performed to predict fabric tension and the effect of fabric stiffness on embankment deflections. The predicted fabric tensions were compared with the results of a sliding block analysis, and show this simple analysis requires further correlation...

  • Effects of soil slope on lateral capacity of piles in cohesive soils

    Creator:
    Nimityongskul, Nontapat
    Abstract:
    Pile supported bridges are typically constructed near or in a natural or man-made slope and are subjected to lateral loading. The current design method for laterally loaded piles involves the use of Winkler's spring concept with the standard nonlinear p-y curves. The available p-y curves were developed based on results...

  • Dynamic behavior of silty soils

    Creator:
    Sunitsakul, Jutha
    Abstract:
    The cyclic resistance of predominantly fine-grained soils has received considerable attention following ground and foundation failures at sites underlain by silt-rich soils during recent earthquakes. In several cases substantial ground deformation and reduced bearing capacity of silt soils has been attributed to excess pore pressure generation during cyclic loading. These...

  • Static and cyclic response of ecoroof soil

    Creator:
    Kraupa, Travis J.
    Abstract:
    Green technology in the United States has been on the rise over the past few decades in the United States. However, certain green technologies have been developed in the absence of design standards. Ecoroofs, which are vegetated soil masses placed on the top of a building’s roof structure, present several...

  • 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....
