桥梁全寿命周期成本分析在工程中的应用

Application of Bridge Life Cycle-Cost Analysis in the Engineering

为了探讨桥梁全寿命周期成本计算模型的可操作性,作者以国内某大桥为例,在专家调查法及评估方法的基础上对桥梁全寿命周期成本构成中桥梁建设期成本、营运期成本和拆除成本进行分析与估算,得出该桥100年的全寿命周期成本为20.76亿元.通过实例计算结果分析进一步证明了桥梁全寿命周期成本分析的必要性.

For the sake of discussing maneuverability of bridge life cycle-cost model,takes a domestic bridge as an example.Base on the method of expert investigation and valuations,analyzes and valuates construction cost,operation cost,backout cost in bridge life-cycle cost.Get the bridge＇s 100 years life-cycle cost is 2076 million yuan.Calculation and result analysis of example further proves the necessity of bridge life-cycle cost analysis.
