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...

Improving Region-Scale Landslide Inventory and Susceptibility Mapping

Creator:

Bunn, Michael D.

Abstract:

Landslides are a natural hazard that have major societal, economic, and environmental impacts. The understanding of landslides begins with the observation that they are a spatial problem. Spatial relationships have historically been explored with maps, and landslides are no different. Such maps range in focus from inventory maps, which identify...

Regional and Site-Specific Vulnerabilities of the Western Power Grid from a M9.3 Cascadia Subduction Zone Earthquake

Creator:

Lathrop Eve D.

Abstract:

The likelihood of a Cascadia Subduction Zone (CSZ) earthquake is estimated between 37 to 42% in the next 50 years, leading to strong shaking, liquefaction, landsliding, and other seismic ground failure resulting in major impacts to critical lifelines such as the western power grid. Electrical power is essential for continued...
