介绍了一种桥梁的检测与维修方案的优化方法 ,并通过具体算例加以说明。最优检测与维修方案在保证桥梁的可靠度指标在全寿命期大于容许限值的基础上 ,使全寿命期的总费用最小。全寿命期费用包括检测费用、维修费用和失效损失三项。本文采用了一个单跨工形钢梁作为算例 ,运用上述方法求解了该钢梁在几种不同情况下的最优检测与维修方案 ,并总结了检测费用、维修费用和失效损失分别对最优检测与维修方案的影响。还指出准确的蜕化模型和费用模型是该方法的关键 A method to optimize bridge inspection and maintenance scheme is introduced and illustrated by a specific example. Optimal inspection and maintenance program to ensure the reliability of the bridge indicators in the whole life is greater than the allowable limit, based on the entire life cycle of the minimum total cost. Lifetime costs include testing costs, maintenance costs and failure of three. In this paper, a single span steel beam is used as an example, and the optimal detection and repair scheme of the steel beam in several different situations is solved by the above method. The detection cost, maintenance cost and failure loss are summarized respectively. Excellent detection and repair program impact. Also pointed out that the exact model of degeneration and cost model is the key to this method
