Probabilistic Engineering Feasibility Study of Tunnel Alignment Selection and Tunnel Design

Doctoral studies at Mines under the advisement of Dr. Marte Gutierrez

Funded by US DOT Grant No. 69A3551747118 and CDOT PO number 471001372

Investigating methodologies for early-stage feasibility studies of transportation tunnel projects, under grant funding from the US Department of Transportation and Colorado Department of Transportation. The project is using the Eisenhower-Johnson Memorial Tunnels as a case study to evaluate probabilistic back-analysis; development of risk-based metrics of excavation and support design based on uncertain geologic information; development of a ranking system for comparison of alternative alignments, excavation methods, and support systems; and impacts of parallel and skew bores on existing infrastructure.

Literature Review of Pseudo-Static Infinite Slope Stability Analyses and Development of a New Equation from First Principles

Consulting work at Geosyntec Consultants for Confidential Client

In support of client’s response to a question from a regulatory agency on a hazardous waste landfill project, Geosyntec initiated a literature review of commonly used infinite slope stability models demonstrating the equivalences and differences between various models. Common questions regarding the applicability and accuracy of these models were presented and answered. A gap in the available models was identified and filled by deriving from first principles a pseudo-static infinite slope stability model considering gas pressure, groundwater seepage, and horizontal seismic loading. Work was presented internally and via project reports to clients. The new model was used as a simple check of more complex numerical models.

Physical Properties of Various Coal Combustion Byproduct Mixtures

Consulting work at ATC Associates for Southern Company

In anticipation of a future need for better disposal or beneficial reuse techniques for coal combustion byproducts (fly ash), Southern Company contracted with ATC Associates to investigate the physical properties of a variety of mixtures of fly ash, gypsum, lime, cement, and flue gas discharge wastewater to determine possible beneficial reuse applications for these waste products. The goal was to avoid landfilling these products or alternatively, to address the most efficient way to place these products into low- or zero-liquid discharge landfills for permanent encapsulation and containment of hazardous materials. Gauen was primarily responsible for performing laboratory testing of these cementitious mixtures. Gauen devised or adapted several procedures to address the difficulties of working with this material. Gauen performed tests for resistivity, time-of-set as judged by hardening of material, unconfined compressive strength, triaxial shear strength, and time-dependent strength properties.
