Civil Engineering professor and interim associate dean for research Anand Puppala has received a total of $465,000 in research funding for the current fiscal year. The largest grant, totaling $212,000, came from the U.S. Army Corps of Engineers. Tasks included in that project are the monitoring of the surficial slope stability issues of the local Grapevine and Joe Pool Lake dams; additional testing that addresses shear strengths of treated soil mixtures; and addressing clay mineralogy issues of different soils from Corps project sites.

“This grant will lead to new methods to stabilize slopes that will mitigate massive large slides as shown in the following photograph and also to include clay mineralogy for better understanding of soil behavior,” Puppala explained.

The Tarrant Regional Water District awarded Puppala $158,000 to study the controlled low-strength material (CLSM) mix design using native clayey soils and addressing durability of the designed CLSM mixes. CLSM is a self-compacted, cementitious material used primarily as a backfill in lieu of compacted backfill.  According to Puppala, successful completion of this study could enhance sustainability aspects as this mix with native clays will result in substantial costing and enhancing reuse of excavated native trench material.

The third project was funded by Fugro Inc. for $95,000. It deals with measurements of sulfates in various soils along the Tarrant Regional Water District Integrated Pipeline alignment. Puppala says this information will be valuable in screening various chemical treatment methods to stabilize sulfate soils along the pipeline alignment.

Dr. Puppala’s research group comprises of two post-doctoral fellows, six doctoral students, and six full-time masters students. Dr. Bhaskar Chittoori, Faculty Associate, is involved in all three projects. Doctoral students Minh Le and Naga Talluri, as well as masters students, Rajanikant, Priya Lad, Justin, Ranjan and Pinit are working on the research tasks. Ken McCleskey and Sarwenaj Ashraf are project directors for the Corps projects, Matt Gaughan of IPL and Shelly Hattan of TRWD are the project directors of TRWD/IPL project and David Lutz and Mark Wilkerson are the project directors for the Fugro project.
