MANAGEMENT STRATEGY GENERATION METHOD FOR EACH BRIDGE AND BRIDGE GROUP CONSIDERING LIFE CYCLE OF BRIDGE, AND BRIDGE MANAGEMENT SYSTEM USING THE SAME

摘要

Provided are a method and a system for establishing the maintenance strategy of an individual bridge and a bridge group in consideration of a life cycle. The method and the system provided by the present invention secure the safety and function of a bridge at a fixed level, reduce maintenance costs by reasonably estimating future maintenance costs through a preventative maintenance, estimate a reasonable and objective future maintenance demand according to the level of a bridge component (member), an individual bridge, and a bridge group, and support a decision making by connecting a function change model and a cost model which are developed based on the life cycle function and cost data of the bridge. The bridge management system which builds the maintenance strategy of an individual bridge and a bridge group in consideration of a life cycle includes: a basic information management unit; a function evaluation unit; a cost calculation unit; an individual bridge strategy generating unit; a bridge group strategy generating unit; a database (DB); and a user interface. The present invention is able to predict a maintenance demand and support a decision making by securing the life cycle performance and cost data of a bridge and performing an optimal maintenance strategy in consideration of the performance and costs of the life cycle of the bridge.
