摘　　要：为了研究桥梁维修决策中桥梁维修期间社会成本核算和最优维修方案选择的问题,文章进行了桥梁维修寿命周期社会成本组成分析、社会成本测度模型分析和维修方案选择模型分析,即在满足桥梁使用功能的基础上,综合考虑桥梁维修的经济成本、社会成本和维修后的再使用寿命,以总成本最小化为目标对不同维修的维修成本和维修后再使用寿命周期进行评估。通过模型分析,选择最优维修方案,提出了以维修寿命周期成本最小化为目标的维修决策模型。To study the problem of social cost accounting and maintenance decision of bridge repair life cycle, the article based on the analysis of the composition of bridge repair life cycle＇s social cost and its measurement model, put forward the selection model of repair scheme to minimize the cost of bridge repair life cycle. This is based on the requirements of bridge function, considering the economic cost and social cost of bridge repair, and its remaining service life. And it assesses the repair scheme which has different repair cost and remaining service life, through tile analysis of the measurement model choice the optimal repair scheme.
