In Print A Sample of Recent Faculty Publications Carlos Carranza-Torres is co-author of the paper "Estimation of support requirement for large diameter ventilation shaft at Chuquicamata Underground Mine in Chile" with Esteban Hormazabal from SRK Consulting, Chile. The paper describes the process of determining the support needs for a ventilation shaft of 22 m diameter and 970 meters depth to be constructed in the new Chuquicamata Underground Mining project, in Calama, Chile. Hatch Ltd. (a company with headquarters in Toronto, Canada) and SRK Consulting (a company with headquarters in Johannesburg, South Africa) are partners with CODELCO (the National Chilean Copper Company) for the engineering design of all underground infrastructure for the new mine development. Carlos Carranza-Torres has collaborated as external geotechnical consultant for the project. The paper will be presented at (and published in proceedings of) the 12th International Congress of Rock Mechanics, in October of 2011, in Beijing, China. Eshan Dave’s paper titled “Viscoelastic functionally graded finite element method with recursive time integration and applications to flexible pavements” is in press in the International Journal of Numerical and Analytical Methods in Geomechanics. The paper describes a novel finite element analysis scheme that is applicable for viscoelastic functionally graded systems, such as aged asphalt pavements. The proposed method yields greater accuracy, and lower computational costs as compared to traditional finite element approach. Co-authors of this work are Glaucio H. Paulino and William G. Buttlar. The paper will appear in the journal later this summer. Andrea Schokker co-authored a paper entitled “LPR Tests on the Corrosion Protection Degree of Post-Tensioning Grouts,” that will be published in the ACI Materials Journal this summer. Co-authors are Dr. Alex Pacheco (Federal University of Rio Grande do Sul, Brazil), Dr. Jeff Volz (Missouri University of Science and Technology), and Dr. Trey Hamilton (University of Florida). Drs. Pacheco and Volz are former PhD students of Dr. Schokker and now hold faculty positions. The paper outlines a new test method for rapidly determining corrosion resistance of grouts for post-tensioning applications. Rebecca Teasley, with co-author Dr. Daene McKinney, had their paper “Calculating the Benefits of Transboundary River Basin Cooperation: The Syr Darya Basin” accepted for publication in The Journal of Water Resources Planning and Management. This paper used cooperative game theory to evaluate a draft agreement on water and power sharing among four countries in the Syr Darya basin in Central Asia. Rebecca Teasley was co-author of “Groundwater Banking in the Rio Grande Basin” with colleagues Dr. Samuel Sandoval-Solis, Dr. Daene McKinney and Dr. Carlos Patino-Gomez from The University of Texas at Austin. Published in January 2011 in The Journal of Water Resources Planning and Management, this paper describes a method of storing groundwater in aquifers for improved water management.
