Engineering Behavior of Remolded Diatomaceous Silts

Creator:: Pitso, Talenta
Abstract:: Diatomaceous soils are a geological material whose engineering properties do not readily conform to the widely accepted and used mechanical and behavioral frameworks. This ambiguity results in design difficulties and geotechnical failures which can be costly. Diatomaceous soils have diatoms in their matrix. Diatoms are unicellular algae with an inert...

Simulation of Heat Transfer Through Soil for the Investigation of Wildfire Impacts on Buried Utilities

Creator:: Richter, Edward G.
Abstract:: Wildland urban interface (WUI) communities in the Western United States have recently dealt with historic and devastating wildfires year after year. The fires have cost tens of billions in damage, burned tens of thousands of structures, displaced thousands of residents, and killed over one hundred people. The 2017 Tubbs fire...

GOSEP: Georeferenced Oregon Soil Engineering Properties

Creator:: Dutille, Victoria L.
Abstract:: Geotechnical engineers design and analyze the interface between the natural and built environments, often based on uncertain and inherently variable data due to the nature of the building material, soil. Engineers must estimate the subsurface conditions at a site using historical, in-situ, and laboratory testing data. However, only discrete representative...

Evaluation and Modification of a Thixotropic Fluid Model for Liquefaction Triggering with Application to Laboratory Tests and Lateral Spreading

Creator:: Brown, Tovey M.
Abstract:: Earthquake-induced liquefaction is a large contributor to damage observed following seismic events. Commonly observed damage consists of significant ground and structural failure due to the deformation of large volumes of soil due to soil liquefaction and lateral spreading. A significant focus of geotechnical seismic research concentrates on the development and...

Evaluating climate change induced coastal flood impacts to San Diego Bay Naval Infrastructure - a hybrid statistical dynamical modeling approach

Creator:: Anderson, Tyler P.
Abstract:: This study utilizes probabilistic surrogate modeling techniques around San Diego Bay with an emphasis on naval infrastructure and operations to evaluate the impact of five global mean sea level rise scenarios (GMSLR). Spatially continuous total water levels (TWLs) are combined with a digital elevation model (DEM) of the region to...

Assessing Durability of Concrete and Ettringite Accelerated Cementitious System

Creator:: Sarkar, Anika T.
Abstract:: The goal of the first part of this project was to investigate the influence of aggregate source and entrained air on the transport properties of concrete. Currently, there are several ASTM standards available that provide systematic procedures to evaluate mass transport properties of concrete. ASTM C642-13 (ASTM 2013), often referred...

Stabilization of landslides along the Oregon Coast

Creator:: Prestedge, Gordon Kendall
Abstract:: The northern Oregon coast suffers extensive loss of land as a result of landslides which constitute the primary mechanism of coastline recession. Both real property and structures along the coast have been destroyed and this destruction will continue. In certain instances, it may be feasible to protect property by engineered...

Structural Effects of Hydraulic Loading and Drainage of Ecoroofs and Preliminary Consideration of Associated Design Loading Scenarios

Creator:: Thompson, Lucas E.
Abstract:: As ecoroofs have become more widespread throughout the U.S., it has become increasingly important to understand their structural behavior. The purpose of this research was to investigate the load effects exerted on a roof structure with an ecoroof during rain events and the subsequent drainage period, with the intention of...

Seamless Topobathymetric River Mapping Through Multi-Sensor Data Integration: Lidar, Sonar, RTK GNSS and Structure from Motion

Creator:: Kellum, Kory and Kellum, Kory E.
Abstract:: Seamless, high-resolution topobathymetric digital elevation models (DEMs) of rivers are important for generating hydrodynamic models, studying water quality and related ecological issues, modeling flood vulnerability, and numerous other applications. However, such DEMs can be difficult to generate, due to a lack of topographic and bathymetric source data. Even where the...

Hydrodynamic loads on fiber-optic micro cables

Creator:: Evans, Matthew R.
Abstract:: A Finite Element Model of a deployed Fiber-Optic Micro Cable (FOMC) was performed using the marine cable modeling software, OrcaFlex. The focus of this study was a parametric analysis of a two-part, towed cable array with the FOMC dragged behind a depressor and connected to a drogue chute. Length-to-diameter ratios...
