摘要

The objectives of this work were (1) to develop an inspection and rating system that uniformly and consistently describes the current condition of miter lock gate structures, and (2) to develop guidelines for the maintenance and repair of these structures. After inspection data are gathered, they are filed on a computer disk through a microcomputer program. The program will then compute the structural and functional condition indexes for miter lock gates. The program user can create a plot of condition index versus time and formulate a number of maintenance and repair solutions from a set of alternatives. Consequences of the various solutions are quantified by reevaluating the condition index. When the initial costs, expected life, downtime costs, interest rates, and inflation rates are known, a preliminary life cycle cost analysis can be performed. With this information, an experienced engineer can make a preliminary maintenance and repair plan for the structure.
