REMR Management Systems - Navigation Structures. Condition Rating Procedures forSector Gates

摘要

As part of the US Army Corps of Engineers' Repair, Evaluation, Maintenance, andRehabilitation (REMR) program, the project team at Iowa State University (ISU) has focused on the evaluation and repair of the sector gate structures within the Corps civilian projects. This report includes a uniform procedure to describe the current condition of sector gate structures. The entire inspection and rating process is based on a field inspection of the sector gate structure. During this inspection, current physical attributes of the systems are obtained. Pertinent data (gate location, inspection and maintenance histories, and historical water level) are recorded on an inspection form. The form also includes space for entering field measurements (anchorage movements, elevation changes, gate deflection, cracks, dents, and corrosion), which are used directly to rate the condition of the gate. This information is used to calculate a condition index (CI), or numerical measure from 0 to 100, of the structure's current state. The index is meant to focus management attention on those structures most likely to warrant immediate repair or further evaluation, and can be used to monitor change in the general condition over time and to serve as an approximate comparison of the condition of different structures.
