摘　　要：针对当前桥梁寿命周期成本理论中缺乏环境影响成本计算方法的问题,引入主要用于环境评估的生命周期评价理论,通过两种理论的详细比较,确定出桥梁寿命周期成本理论中关于环境成本的考量方式和各阶段应考虑的成本类型,并指明其对应的的计算方式。以某公路桥梁为例,详细说明了各阶段成本的计算过程。研究成果进一步完善了桥梁寿命周期成本理论的分析模型,拓展了其应用范围,为桥梁全寿命设计方法的实施和推广提供了分析基础。Up to present, the theory of bridge life-cycle cost lacks a method to calculate the cost of environmental impacts, therefore, a theory of life-cycle assessment is introduced to mainly assess the environment impacts. A detailed comparison of the two theories is made to determine the ways to concern the environmental cost and the cost types at different stages in the theory of bridge life-cycle cost, and to point out corresponding calculation methods. A road bridge was taken as an example to elaborate the calculation process of cost at different stages. The research findings further improve the analysis model of the theory of bridge life-cycle cost, expand its application range, and provide an a-nalysis basis for the implementation and promotion of the design method for full bridge life cycle.
