Stability Analysis Of The Slope Along Us-2 Between Epoufette Bay And The Cut River Bridge, Stephanie Watts-Garcia
Dissertations, Master's Theses and Master's Reports - Open
Recently, water was observed flowing from a section of steep slope along US-2 near St. Ignace, Michigan in addition to soil sloughing in the area where the water is flowing from the slope. An inspection of the area also showed the presence of sinkholes. The original construction drawing for US-2 also indicated that sinkholes were present in this area prior to road construction in 1948. An investigation was conducted to determine the overall stability of the slope. The slope consists primarily of aeolian sand deposits. Laboratory testing determined the shear strength of the slope material to have a friction angle …

Measurements And Transient Multistep Outflow Simulation Of Soil-Water Characteristic Curve For Soils Modified With Biopolymers, Xiaoyi Zhao
Masters Theses
"In recent decades, biopolymers have shown promising applications in soil modification due to its environmental friendly nature. Most of the studies, however, focused on mechanical properties at saturated or unsaturated conditions. The study on unsaturated soil behaviors under controlled pore air and pore water pressures were limited. Soil-water characteristic curve (SWCC), relating water content with matric suction is a key property to evaluate unsaturated soils. With SWCC, other soil properties, such as hydraulic conductivity and shear strength can be estimated. In this study, SWCC of sands modified with different biopolymers were measured with both Tempe cell and Fredlund SWCC device. …

University of Mississippi. Sally McDonnell Barksdale Honors College
Design Considerations For A Rotating Retractable Stadium Roof, Charles S. Jenkins
Honors Theses
This thesis presents a novel type of retractable roof, adapting the pivot-based retraction system used in Miller Park to a stadium without a circular geometry. Existing stadiums with retractable roofs are reviewed, and lessons learned are used to present theoretical structural engineering design for a roof truss and recommendations for carriers. The presented concept likely requires light-weight structural systems and closely-spaced roof trusses to minimize loads on roof carriers. Actual mechanical designs of the roof carriers are quite complex as they must be able to roll in two directions and pivot about a third. The design herein is incomplete for …
