寿命周期成本分析方法在桥梁工程中的应用

Application of Life Cycle Cost Analysis Method to Bridge Structures

桥梁耐久性低、服务寿命短的问题已经严重影响了结构正常服务功能的发挥 ,并给社会造成了巨大的经济负担。文中介绍了寿命周期成本分析的概念及其应用于桥梁工程的发展历程 ,阐述了它的基本原理 ,探讨了桥梁寿命周期成本的构成 ,并给出了进行分析时的计算公式。

Normal service performance of bridges is suffered from poor durability and short lifetime which have brought great economic burden for society. The concept of life cycle cost analysis and its application history in bridges are introduced. The compose of life cycle cost is discussed and calculation equation presented. And importance of LCCA for bridges design and maintenance is explained by two examples in foreign countries.
