Repair, Evaluation, Maintenance, and Rehabilitation Research Program: REMR Management Systems-Coastal/Shore Protection Structures: Condition Rating Procedures for Rubble Breakwaters and Jetties. Initial Report.

摘要

This is an initial report on the development of a basic system for uniformly evaluating the condition of breakwaters and jetties of all--or primarily--rubble construction with either rock or concrete armor. This system is based on visual inspection and uses numbers on a scale from 0 (worst) to 100 (best) to represent the relative condition of the structures. The process begins by assessing the crest (or cap), seaside, and leeside of each reach (section) of a structure according to a standard list of structural aspects. This assessment, in turn, leads to ratings for the seaside and leeside slopes and crest of the reach. Then, the reach ratings are combined to give a single, overall condition rating for the whole structure. The condition rating system considers both structural and functional aspects of the structures. The intent of this system is to provide a consistent method for evaluating condition that supplies numerical condition descriptors that can be handled easily on a microcomputer. This numerical system aids in the maintenance planning process by permitting the condition to be monitored over time and by allowing a relative condition comparison between structures.
