混凝土梁桥全寿命成本计算探析--福建泉州东埭大桥为例

Analysis of life cycle cost calculation of concrete girder bridge--Dongdai bridge in Quanzhou,Fujian Province as an example

基于我国传统的重视桥梁建设成本而轻视桥梁养护成本做法的不足,结合工程经济学和桥梁养护规范,按照建设前期成本、建设期成本、运营期成本和拆除成本四大分项建立混凝土梁桥全寿命周期成本模型,并通过东埭大桥实例验证模型的可行性。

On the basis of the traditional method of attaching importance to the cost of bridge construction and neglecting the cost of bridge maintenance. Based on the engineering economics and bridge maintenance code,this paper establishes the life cycle cost model of concrete girder bridge according to four sub items: pre construction cost,construction cost,operation cost and demolition cost. The feasibility of the model is verified by an example of Dongdai bridge.
