COURSE DEVELOPMENT

New Courses (Six)

· Both CE 4300/CE 4322 (Applications with Geosynthetics) and CE 5372 (Geosynthetics) courses were offered first time in spring, 1997. These courses were introduced in graduate geotechnical engineering and undergraduate civil engineering curricula to teach students about applications of geosynthetic materials in infrastructure construction. Students were exposed to design, analysis and construction of geosynthetics in soil separation, drainage, pavement and embankment reinforcements, stabilized retaining walls and landfill applications.

• CE 5371 (Soil Behavior), a new graduate course was offered for the first time at UTA in summer, 1998. This course covered all theories and mechanisms that explain different soil behaviors in real field conditions. This is a core course for graduate studies in geotechnical engineering.

• CE 5373 (Environmental Geotechnology), a graduate course was offered first time in fall, 1997. The main intent of this course was to teach soil contamination issues, transport of contaminants in soil media, remediation methods, landfill designs, and environmental regulations.

• CE 6382 (In Situ Testing and Interpretation), an advanced graduate level course was offered first time in summer, 1997. The main objective of this course was to teach several geotechnical in situ methods and their applications for soil characterization, settlement evaluation and infrastructure foundation design.

• CE 6312 (Advanced Foundation Design), a new advanced graduate course was offered for the first time in fall, 2003. This course covered design methodologies for deep foundation systems (isolated and combined systems) subjected to axial, lateral and group loads as well as combinations of loads acting at the same time. Foundations in expansive soil environment were also covered.

• CE 5300 (Ground Improvement), a new graduate course was offered for the first time in Spring 2006. This course covered design mechanical modification methodologies, hydraulic modification methods, chemical modification methodologies and thermal modifications. Case study topics related problem soils, grouting and deep mixing technologies were also covered.

Revised Courses (Four)

• CE 3143 (Soil Mechanics Laboratory) was significantly revised and offered in spring 1997. Project-oriented laboratories were introduced in this course. Students learned about the experimental design and laboratory testing, analysis and graphical presentation of results, report writing and teamwork concepts.

• CE 4321 (Foundation Design) and CE 5364 (Foundation Design and Analysis) courses were offered by revising earlier courses. The revised courses introduced shallow and deep foundation designs as well as pile design methods based on load tests.

• CE 5365 (Theoretical Soil Mechanics) course was revised and offered in fall, 1996. This course taught advanced geotechnical concepts such as critical state theories, liquefaction, and advanced consolidation theories and numerical method applications

• CE 5370 (Experimental Soil Mechanics) was revised to teach and prepare graduate students on advanced soil characterization laboratory methods including strength, swell and shrinkage tests as well as soil chemical characterization methods. Statistical design methods and analysis, and applications of analytical models to simulate laboratory tests were introduced for the first time.
