摘要
为系统阐述全寿命周期成本分析的桥梁设计的研究现状,介绍了全寿命周期成本分析的研究背景、基本概念和原理,综述了寿命周期成本分析方法在桥梁结构全寿命设计方案决策的研究现状、关键技术和使用前景。总结国外全寿命周期成本基本理论体系,对全寿命周期成本模型和框架的研究进行了介绍,将两种最具代表性的模型进行了对比。归纳了近年国内桥梁全寿命周期成本的构成以及计算方法的研究概况,指出寿命周期成本主要由管理单位成本、用户成本和社会成本组成,分析了计算成本各组成部分中的困难,总结目前基于全寿命周期成本的桥梁设计中存在的问题。为基于全寿命周期成本的桥梁全寿命设计、维护、投资方案决策以及桥梁管理系统开发提供必要的研究背景。
In order to systematically expound the research situation of bridge design based on concept of life cycle cost（LCC） analysis,the research background,basic concept and principle of LCC analysis were introduced.The research status,the appropriate key technologies,and the prospects of LCC analysis for bridge design were illustrated.The study of basic theoretical system of LCC on board was summarized.The models of LCC and the study of framework were showed.The two most representative models were compared.The composition and calculation method of the bridge life cycle cost（BLCC） at home were introduced as well.LCC consists of per-unit cost of management,cost of users and social cost.The difficulties and obstacles encountered in calculation of the components were analyzed,and the existing problems in bridge design based on LCC were summarized.The study presented a necessary background for bridge design,maintenance,investment decision-making and the development of bridge management system based on LCC.
