Stability of heterogeneous and anisotropic slopes determined by the compound logarithmic spiral limit equilibrium method

Creator:: Stockton, Ezra J.
Abstract:: The logarithmic-spiral (log-spiral) limit equilibrium procedure for slope stability analysis rigorously satisfies both force and moment equilibrium with a failure surface geometry formulated as a function of the soil’s angle of internal friction. Within the framework of limit equilibrium, this procedure has, in the past, been primarily limited to homogeneous...

Evaluation of straw wattle placement and surficial slope stability

Creator:: Rikli, Anthony M.
Abstract:: Straw wattles are common erosion control devices used to trap sediment. This thesis studies the relationship of straw wattles on slope stability through a case study demonstrating their use on steep slopes (1.5H:1V) for the US20 highway realignment project. Several surficial slope failures have occurred on these fill slopes, often...

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...

Pore Water Pressure Response in Soil During Tsunami Loading : Numerical Formulation and Experimentation

Creator:: Abdollahi, Abbas
Abstract:: Tsunami loading can cause sediment instability, which can compromise the structural integrity of coastal buildings and infrastructure. To understand the process by which a tsunami can cause sediment instability, it is necessary to understand how the pore water pressure in the soil changes during tsunami loading. Tsunami run-up causes the...

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...

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...

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...

Characterization of reinforced fill soil, soil-reinforcement interaction, and internal stability of very tall MSE walls

Creator:: Walters, James J.
Abstract:: In many geotechnical design situations involving tight right-of-way constraints, Mechanically Stabilized Earth (MSE) walls are often the most cost-effective and reliable earth retention technology among available alternatives. However, few well-documented case histories with detailed material testing, instrumentation programs and construction observation of performance are available in the literature. Despite the...

Analysis and operational considerations of biomass extraction on steep terrain in western Oregon

Creator:: Flint, Benjamin R.
Abstract:: The development of bioenergy from biomass has dominated the minds of forest engineering researchers over the last decade. One of the main themes that has been generated from that research is that bioenergy from biomass has major operational hurdles to overcome before becoming economically feasible. More directly, the impact of...
