Repair, Evaluation, Maintenance, and Rehabilitation Research Program: User's Manual: Inspection and Rating of Steel Sheet Pile Structures

摘要

For much of its early history the U.S. Army Corps of Engineers was heavily involved in the design and construction of new facilities, but now the mission of the Corps is shifting from construction to the maintenance of existing facilities. The Corps has addressed its changing role by instituting a Repair, Evaluation, Maintenance, and Rehabilitation (REMR) program. As a part of this program, a project team at Iowa State University has undertaken a research effort that focuses on the evaluation and repair of the steel sheet pile structures within the Corps' civilian projects. These structures do not require a great deal of maintenance but failure of a steel sheet pile wall can significantly affect operations--especially as part of a lock and dam facility. In the following document, a general description of the current inspection and rating system is given. This includes the definition of a condition index and a brief description of sheet pile distresses. A detailed description of the inspection process follows. Once the inspection data have been gathered, they are entered onto a computer disk through a personal computer (PC) program. The description provides sufficient detail for a trial application of the inspection process. Keywords: Structural engineering; Repairs; Inspection. (KT)
