摘　　要：基于生命周期评价和生命周期成本分析理论,将桥梁工程生命周期从环境属性和经济属性两方面考虑,环境属性为生命周期环境影响(输出过程),经济属性为与环境因子有关的生命周期成本(输入过程),提出一种将与环境因子有关的生命周期成本(输入成本)与生命周期环境影响成本(输出成本)相集成的方法。对比分析武汉徐东高架桥两种设计方案(A:混合梁桥,B:钢箱梁桥),得出钢箱梁桥比混合梁桥综合成本低,为桥梁方案比选提供依据。Based on the theory of life cycle assessment （I.CA） and life cycle cost analysis （LCC）, the life cycle of bridge engineering was considered from two sides, environmental properties and economic properties. The former was regarded as environmental impact in bridge engineering life cycle（output process）, the latter as engineering life cycle cost related to the environmental {actors （input process）. Then,a new method to integrate LCC related to those environmental [actors （Input costs） and to the life cycle environmental impact cost （output costs） together was put forward. And this new method was used in the calculation o{ comprehensive cost of two designs （program A is hybrid girder bridge, program B is steel box girder bridge） of Wuhan Xudong Viaduct , the result shows that steel box girder bridge is better than hybrid bridge. The research was of great help in providing reliable basis for choosing bridge programs.
