TRI Education: Slope Stability & Interface Friction Short Course, May 7 – 8

Slope CourseTRI Environmental hosts high-level engineering education events with immediately implementable solutions. On May 7 & 8, the company will offer a two-day course on “Slope Stability of Containment Systems: Understanding Issues Related to Design and Interface Friction Testing.”

Location: TRI Environmental’s international headquarters in Austin, Texas.

The slope stability short course is led by Dr. Jeffrey Kuhn, P.E. (TRI) and Dr. Ranjiv Gupta, P.E. (Freeport-McMoRan). The team first presented the course a year ago, and demand for another session has been strong. For the first time, TRI has added the course to its annual spring training week courses. Additional education offered between May 7 and 11 includes two one-day field CQA courses (geosynthetic installations and GCL/CCL installations).


“Slope Stability of Containment Systems: Understanding Issues Related to Design and Interface Friction Testing” provides insight from the independent testing and geoenvironmental consulting & owner’s perspectives on a wide range of containment structures (e.g., municipal and hazardous waste landfills, coal ash surface impoundments, heap leach pads). These facilities are constructed using multiple layers of geosynthetic materials such as geomembranes, geotextiles, geonets, geocomposites, and geosynthetic clay liners (GCL). The design of a containment structure not only requires an understanding of the properties of each individual geosynthetic material but also the ability to comprehend the interaction mechanism (friction) between various geosynthetic layer interfaces.

Slope Course smallerThis course, worth 8 PDHs, is specifically targeted to those persons who have a need to understand and specify interface friction and direct shear tests; and who use these results in subsequent design, construction, and monitoring performance of containment structures.
