Field Monitoring Of A Tieback Wall And Comparison To Common Design Methods, Matheus Barbosa Santos De Miranda

Graduate Theses - Civil Engineering

This thesis presents the monitoring of a 28-foot high retaining wall located on the Rose- Hulman Institute of Technology (RHIT) campus and compares inclinometer and load cell data with common design methods. In addition, it briefly provides discussion regarding how the retaining structure is used to enhance student learning. The wall consists of soldier piles and wood lagging with tiebacks that vary from 22.5 to 40 feet. Construction was completed in 2017. Instrumentation, including load cell and inclinometers were installed to measure deflection, tieback load, and water level. This thesis describes the construction activities and the data gathered to date. …

Reduction Of Pertechnetate From Off-Gas Condensate Using Aged Zero-Valent Iron As A Reducing Agent, Abraham T. Gebru

FIU Electronic Theses and Dissertations

The Hanford site located in Washington State was one of the major nuclear processing facilities in the U.S. where plutonium was produced between the 1940s and the 1980’s. As a result of this forty yearlong production, approximately 53 million gallons of radioactive waste was generated and currently stored in 177 single and double shelled underground tanks. There were around 60 major and minor leaking incidents in the tanks through the years. These leaking incidents were wakeup calls to a search for an effective long term disposal solution. This paper will concentrate on the low activity waste (LAW), specifically the radioactive …

Boy Scouts Of America Concept Site Master Plan And Improvements, Anna Cole, Jacob Chekal, William Seeger, Shanon Al-Brady, Nicholas Cowles

Honors Theses

Our team, G1 Engineering, has partnered with the Boy Scouts of America to provide an update to their master plan for the Outdoor Education Center site located at 600 S. 120^th Street, Lincoln, NE. Our work included providing transportation solutions; drainage evaluations; investigation of geotechnical conditions; environmental evaluation and determination of permitting requirements; preparation of concept design plans for bridges, drainage, utilities, and overall site plan; and evaluation of structural elements included in the project.

Two streams cross the property presenting site access issues. Our team provided pedestrian, UTV, and emergency vehicle access bridges to address these issues. With …

Outdoor Education Center Concept Site Master Plan And Improvements As Designed By Wingineers, Christina Thibodeau

Honors Theses

This thesis builds on a basis of four years of engineering education to produce a final project for the capstone course. The idea behind this project was to provide a workable master plan and conceptual site improvements for a real application, the Outdoor Education Center in east Lincoln, Nebraska. The Boy Scouts of America Cornhusker Council and the University of Nebraska – Lincoln Department of Civil Engineering have cooperated throughout the Senior Design capstone course to make this possible for the students involved.

Behavior Of Geothermal Energy Piles Embedded In Rock, Ehab Sabi

Civil and Environmental Engineering Theses and Dissertations

Geothermal energy piles are categorized as closed systems. Energy piles are a relatively new technology which couples the structural role of traditional pile foundations to that of heat exchangers to fulfill the required energy demand of buildings and infrastructures. These foundations are equipped with pipes embedded in the concrete forming the pile. While connected to a heat pump, the fluid circulating inside these pipes provides the exchange of heat with the ground for heating and cooling purposes. As the undisturbed temperature at the shallower depths of the ground stays comparatively constant the whole year, being warmer than the surrounding temperature …

Investigation Of Dredge Material Dewatering Through Hydraulic And Ground Improvement Methods, Monica Moody

Williams Honors College, Honors Research Projects

Every year almost 1.5 million tons of material is dredged from Lake Erie to allow passage for boat traffic. In the past, this material has been placed back into the open waters of the lake. However, starting July 2020 this will no long be permitted due to the passing of Senate Bill 1. Therefore, secondary uses of this dredging material are being investigated. To be used, the material needs to be quickly dewatered and stabilized. This project consists of literary reviews of two methods of rapid dewatering, hydraulic placement and ground improvement methods. Hydraulic placement dewatering requires the use of …
