Acoustic Emission Monitoring of Cofferdam Performance, Locks and Dam 26 (Replacement)

Abstract

A research program consisting of measuring acoustic (microseismic) emissions generated on and within the circular cofferdam cells was conducted. The purpose of the study was to correlate the acoustic emissions with the forces acting on the cofferdam and the resulting movements and stresses caused by such forces. Keywords: Acoustic emissions; Cofferdams; Sheet pile cells.
