In-Flight Excavation of Slopes with Potential Failure Planes
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 142, Issue 5
Abstract
The stability of an in-flight undercut slope with a potential failure plane was investigated under a centrifugal acceleration of . The experimental results confirmed the formation of passive arch action in the undercut slope and were found to be in good agreement with the results of physical model tests showing that the arching-type failure in undercut slopes is a scale-independent phenomenon. The maximum stable undercut span is compared with that in the theory developed by the authors, and the results are discussed.
