HYDRAULIC STABILITY OF ARTICULATED CONCRETE BLOCK REVETMENT SYSTEMS DURING OVERTOPPING FLOW. FINAL REPORT

Initial investigations of articulated concrete block revetment systems were performed as part of an overall study to examine methods of protecting earth embankments during overtopping flow. The results of the initial study are presented in Report No. FHWA-RD-88-181. The favorable performance of these earlier tests resulted in additional and more detailed investigations which are presented in this report. In this study, the hydraulic characteristics and stability of articulated concrete block revetment systems in high-velocity overtopping flow are examined. Seventeen hydraulic tests were performed on five different revetment systems, including cable and uncabled installations. Eight of the tests were conducted over a rigid concrete test embankment, while the remainder were conducted over an embankment made of highly erosive soil. Hydraulic data were collected both above and below the revetment system, the latter being accomplished through the use of a remote pressure transducer network. Relationships involving pressure, velocity, depth, and slope on the stability and resistance to flow are developed and presented.
