| 摘 要： | 针对桥梁结构的耐久性问题日趋突出,为在桥梁养护过程中降低养护成本,使养护资金更有效地投入到桥梁养护生产上来,使公路养护管理进入良性循环状态,进行桥梁养护的成本效益分析是重要的管理环节.提出了基于可靠度理论的桥梁养护成本效益分析模型,即维修方案比选的原则是保证目标可靠度,使维修效益与成本的比值最大化.然后以一座实桥为简单算例验证了该模型的合理性.分析结果表明,采用合适的成本效益分析方法,能为今后的桥梁养护工作提供进一步节省成本的方向和途径.

| Abstract: | The availability of maintenance cost and benefit analysis has been proved by lots of actual projects.It can decrease the maintenance cost,and improve the efficiency of funds.Based on comparison and analysis of the maintenance models of bridge existing in the world,a new model for maintenance is proposed for analysis of comprehensive target reliability and maintenance cost and benefit.The principle of selecting maintenance projects is to maximize the ratio of maintenance benefit to cost on the premise of ens... |
