摘要

The Army Corps of Engineers is shifting emphasis from designing and constructing new facilities, maintenance of existing facilities. This research focuses on the evaluation and repair of the steel sheet pile structure. The objectives of this work were to (1) develop an inspection and rating system that uniformly and consistently describes the current condition of steel sheet pile structures, and (2) develop guidelines for maintenance and repair of these structures. This report discusses the current inspection and rating system and provided the definition of a condition index and a brief description of sheet pile distresses. A detailed description of the inspection process is included. Inspection data are entered onto a computer disk through a PC program that summarizes the safety and serviceability problems associated with the structure. By supplying the initial costs, expected life, downtime costs, interest rates, and inflation rates, an experienced engineer can make a preliminary maintenance and repair plan for the structure.
