Mr. Kuhne’s Abstract

This site at mile marker 7 on I-40 had been identified for decades as a textbook planar failure in-waiting. By 2013, the site had failed twice, blocking the westbound travel lanes, and required yearly inspection and maintenance in the form of seasonal slope scaling. Fortunately the two major incidents occurred while the interstate was under closure for other reasons. NCDOT decided the situation risk was intolerable and instigated an improvement project to re-engineer the slope. The slope exhibits imperfect planar failure conditions and required design and construction details to deal with future rockfall, even though the primary threat was removed. This presentation will examine design inputs, final design considerations and construction items required to construct a safe rock slope with an emphasis on how NCDOT approaches rock slope design in general. This project was completed in 2016.

Mr.Kuhne’s Résumé

 

Mr. Kuhne has been employed by the NCDOT Geotechnical Engineering Unit since 1992. This experience has included geotechnical field work, investigation and mapping, design, and project and office management. He has extensive experience in landslide mitigation including soil, rock, scour and embankment failure. He currently serves as the Regional Geological Engineer for the three mountain Highway Divisions of NCDOT. He received a BS in Geology from UNC Chapel Hill and is a Licensed Geologist and Professional Engineer in NC. He has served on the steering committee for the Geohazards in Transportation in Appalachia group and on the Rockfall and Engineering Geology Committees of the Transportation Research Board. He has authored numerous presentations and publications in Engineering Geology.
