Acoustic Emission on Cofferdam Distress Warning System and Ancillary AcousticEmission Monitoring; Melvin Price Locks and Dam. Phase 3

摘要

A research program was conducted to develop a cofferdam distress warning systemand monitor the acoustic emissions generated by the third-phase cofferdam of the Melvin Price Lock and Dam. The purpose of this study was to extend existing understanding of acoustic emission (AE) within large sheet-pile cell stractures to the design, configaration, and operation of a cofferdam Distress Warning System (DWS) capable of automatic operation for an extended period and to correlate the acoustic emissions with the forces acting on the cofferdam.
