Multi-Stage Shear Testing Of A Cohesionless Soil, Robert Clyde Gullic

Masters Theses

"The multi-stage test is a procedure by which a soil's shear strength parameters can be evaluated by the use of a single sample of the material. The object of the investigation is to evaluate to what extent multi-stage testing can be used on a cohesionless material. Three types of tests, using conventional and multi-stage procedures are evaluated. They are: direct shear/consolidated drained, triaxial compression/consolidated drained and triaxial compression/consolidated undrained shear tests. It was found that multi-stage testing can easily be performed and the shear strength parameter theta_f obtained from these tests are in good agreement with those obtained from …

Parameters Effecting The Dynamic Properties Of A Saturated Cohesive Soil Tested In Cyclical Simple Shear, William Kenneth Andrew V

Masters Theses

"Cyclical simple shear tests were performed on block samples of a remolded clay mixture of 3 parts kaolinite to 1 part of bentonite mixed at 110% water content. The samples had base sizes of 8x8, 4x4, and 2x2 inches square and heights of 1, 2, 4, and 8 inches. The simple shear tests were performed by using a predetermined sinusoidal displacement, at frequencies of 1, 2, and 5 hertz. The shear modulus which was normalized by dividing it by the shear strength, and the hysteretic damping factor which was expressed as the percent of critical damping, were evaluated from a …

A Proposed Concept For The Rapid Field Design Of Protective Structures, John Ross Childress

Masters Theses

"This investigation proposes a simplified concept for the rapid field design of protective structures, subject to attack by conventional artillery rounds, mortar rounds and small rockets. Parameters which should be considered during a rigorous design process are discussed. The number and complexity of these parameters make the rigorous design procedure too unwieldy to be efficiently used, in a limited time period, when materials are not available to comply with Standard Designs. Since the duration of an explosion pulse is very short and uncompacted soil is capable of absorbing explosive energy, this study investigates the theory that adequate protection can be …

Shear Strength Characteristics Of Crushed Glass, Fred Ray Browning

Masters Theses

"Drained and undrained triaxial compression tests were performed on two gradations of crushed glass in order to determine the compressibility and shear strength characteristics. Consolidation pressures varied from 10 to 100 psi. Volume changes during consolidation were discussed because of the dependency of shear strength behavior on the density condition at the end of consolidation. Stress-strain-volume change characteristics were observed in order to discuss the load-deformation and dilatancy relationships and the effects of varying density, gradation and consolidation pressure. Stress-strain properties were also determined for the undrained tests. The undrained tests were constant volume tests, thus having no dilatancy effects. …

A Socio-Economic Traffic Demand Prediction Model Based On A Lumped System Approach, John Edward Thompson

Masters Theses

"The objective of this investigation was to devise a method for predicting transportation system demand based on socio-economic variables of certain physical areas. This pilot study was performed utilizing traffic flow, but minor mathematical alterations could change the transportation system to urban mass transit usage demand. An area of uniform socio-economic characteristics can be delineated and the socio-economic characteristics isolated. Each area will place a distinct demand on some existing transportation facility based on those characteristics. The physical demand can be approximated by a theoretical probability distribution. Once this internal flow generation has been approximated by the frequency distribution, it …

Clay Mineralogy And Compaction Characteristics Of Residual Clay Soils Used In Earth Dam Construction In The Ozark Province Of Missouri, Arthur David Alcott

Masters Theses

"The clay mineralogy and Standard Proctor compaction characteristics of clayey residual soils developed on the Salem Plateau of the Ozark Physiographic Province and used in earth dam construction were studied. A review of the geology of the Salem Plateau is presented along with a discussion of the factors controlling the development of soils on carbonate bedrock in a high leaching environment. The predominant soil clay mineral was found to be a poorly crystallized kaolinite rather than halloysite as has been postulated by others. Minor amounts of triple-layer minerals and an undetermined amount of an alumino-silicate gel are indicated. The effects …

Evaluation Of The Carbon Adsorption Method With Parallel Solvent Extraction Studies, Stanley Kent Wagher

Masters Theses

"In spite of the importance of the carbon adsorption method (CAM) in determining drinking water quality and its wide use in research and plant control studies, little work has been undertaken to quantitatively and qualitatively evaluate the method, especially under field conditions. This investigation was, therefore, undertaken in order to develop a test system consisting of equipment and procedures which would make possible the field evaluation of the carbon adsorption method by parallel solvent extraction studies, and to employ this system in preliminary field investigations to establish guidelines for the experimental conditions required for its effective application. The test system …

A Study Of Precipitation Characteristics For Utah, Tsing-Yuan Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Data on monthly precipitation for three areas of Southern Utah--Beaver, Cedar City and Ephraim--and three areas of Northern Utah--Salt Lake City, Ogden and Logan--where a series of measuring stations were arranged as traverses from the valleys to the mountain tops; were assembled and analyzed.

The relationships between elevation and precipitation amounts were shown. The Southern Utah stations were drier at the same elevations than the Northern Utah stations and the differences became greater as the elevations increased. There was a close correlation between the high elevation and low elevation stations in the same traverse even with the above divergence.

Some Aspects Of Aerated Open-Channel Flow At Shallow Depths And Low Velocities, D. L. Fread

Masters Theses

"This study is concerned with the effect of entrained air bubbles on the open-channel hydraulics of water flowing at low velocities. The air bubbles are introduced into the flowing water by injecting diffused compressed air along the channel bottom. The variations of the velocity profile and velocity distribution energy coefficient of aerated and nonaerated flow are discussed. Empirical equations have been determined for the air concentration and increased depth of flow or "bulking" of the aerated open-channel flow. The investigation revealed a significant increase in the Manning roughness coefficient and the related Darcy friction factor for aerated flow relative to …
