Penetration In A Graded Filter, William Chuan Shen

Masters Theses

"An experimental laboratory study conducted to examine clogging within and penetration of fines into a single layer graded filter. Hydraulic gradient, filter gradation and flow direction were varied. Forty one tests gave over six hundred individual penetration depths. The magnitude of penetration in filters with considerable variation in gradation patterns correlated with an average hydraulic radius based on the volume of voids and an approximated total surface area. It has been shown than an increased thickness of poorly graded filter will stop penetration such as that caused by seepage erosion. A relationship between hydraulic radius, penetration depth and probability of …

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 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 …
