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...

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...

Soil engineering properties and vegetative characteristics for headwall slope stability analysis in the Oregon coast range

Creator:: Bransom, Mark
Abstract:: Six headwalls in the central Oregon coast range were selected for study of soil engineering properties and vegetativecharacteristics important for analysis of slope stability. The headwalls were considered representative of those which would be candidates for timber leave areas due to geomorphic and topographic features, including steepness of slope and...

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...

Morphometric analysis of landslides and slope stability on the north shore of the John Day Reservoir, Columbia River, Oregon and Washington

Creator:: Woelke, Franziska
Abstract:: The John Day Reservoir, a large reservoir between the John Day and the McNary Dams on the Columbia River, must be lowered several feet below design level during salmon migration season in order to preserve anadromous fish habitat. This research assessed the north shore of the John Day Reservoir for...

Spatial analysis of soil depth variability and pedogenesis along toposequences in the Troodos Mountains, Cyprus

Creator:: Robins, Colin R.
Abstract:: In unstable landscapes, modern pedological research explores the role of soils as products and indicators of geomorphologic change. Understanding the dynamics of hill slope pedogenesis is especially important in regions with limited, poor, or threatened soil resources. The island of Cyprus, situated in the eastern Mediterranean, is claimed by many...
