Safeguarding rail infrastructure has been one of the focus areas of Dr. Surya Congress’ research. Check out how we are deploying unmanned aerial vehicles (UAVs) for monitoring and safeguarding rail infrastructure assets in our recently published article: Congress, S. S. C., Puppala, A. J., Kumar, P., Banerjee, A., & Patil, U. (2021). Methodology for Resloping of Rock […]

Journal Paper: Geotechnical Slope Stability and Rockfall Debris Related Safety Assessments of Rock Cuts Adjacent to a Rail Track Using Aerial Photogrammetry Data Analysis
Do you know, with 140,000 route miles, the freight rail network in the United States is widely considered the largest, safest, and most cost-efficient freight system in the world. It is necessary to monitor the rail corridors frequently to maintain safe operating conditions. Our research group is using cutting-edge sensors to monitor the rail corridors. […]
Journal Paper: Forensic Analyses and Rehabilitation of a Failed Highway Embankment Slope in Texas
Though carefully designed, engineering projects may fail for reasons unforeseen and difficult to determine after the fact. For a proper forensic analysis of the causes of any failure in a system, experiments and tests need to be developed and performed. Find out how our team is doing just that in Forensic Analyses and Rehabilitation of […]
Journal Paper: Role of Crystalline Silica Admixture in Mitigating Ettringite-Induced Heave in Lime-Treated Sulfate-Rich Soils
Sustainability and recycled materials are becoming cornerstones of new engineering processes. Waste products such as crystalline silica have a potential for treating sulfate rich soils. Find out more about how our group’s research on the use of this waste product in our paper, Role of Crystalline Silica Admixture in Mitigating Ettringite-Induced Heave in Lime-Treated Sulfate-Rich […]
Journal Paper: Seismic Slope Stability Analysis of a Hydraulic Fill Dam
Slope stability is a very important criteria for earthen dams, especially during earthquake events. Though current practice considers both static and pseudo-static analysis, new approaches may be more accurate and effective for slope analysis. See our new paper, Seismic Slope Stability Analysis of a Hydraulic Fill Dam, for information on this new method. You can […]
Journal Paper: Geomaterial Characterization and Stability Assessment of Hydraulic Fill Dams
Large changes in the soil composition of earthen dams can lead to seismic response that is difficult to predict. 3D models of material properties may help improve future earthquake response at dams with high geomaterial variability. Find out how our group is addressing this challenge in Geomaterial Characterization and Stability Assessment of Hydraulic Fill Dams. […]
Journal Paper: Evaluating the Performance of Wicking Geotextile in Providing Drainage for Flexible Pavements Built over Expansive Soils
Expansive soils can wreak havoc on roadway pavements leading to cracking, rutting, and differential heaving. To remedy this issue, research focus is being put into the use of wicking geotextiles. Recently, our group has published an article on just this issue, Evaluating the Performance of Wicking Geotextile in Providing Drainage for Flexible Pavements Built over […]
Journal Paper: Seismic Response Analysis of a Hydraulic Fill Dam
Current seismic analysis for the natural frequency of hydraulic fill dams is limited to small strains. Therefore, new and improved methods of 2D analysis need to be created in order to expand the picture of earthen dam earthquake analysis. Our article, Seismic Response Analysis of a Hydraulic Fill Dam, explores this topic and presents our […]
