摘要
针对城市轨道建设方案比选和决策问题,建立了考虑资金时间价值的城市轨道交通广义全寿命周期成本模型。分析了城市轨道交通外部成本构成,提出了城市轨道交通阻断成本概念,并构建了城市轨道交通阻断成本模型。以石家庄城市轨道交通1号线为例,定量计算了城市轨道交通不同线路敷设方式广义全寿命周期成本。计算结果表明:采用传统的全寿命周期成本评价方法,城市轨道交通地面线的全寿命周期成本为72.16亿元,成本最低;引入阻断成本的广义全寿命周期成本对各方案进行评价,地下线的广义全寿命周期成本为173.45亿元,总成本最低,为最优方案。
A generalized life cycle cost model was presented in order to solve the selection and decision of construction schemes for urban rail transit,and the time value of capital was considered.The external cost components of urban rail transit were analyzed,the blocking cost concept of urban rail transit was introduced,and a blocking model was developed.A case study of line 1 for Shijiazhuang urban rail transit was made,and the generalized life cycle costs of different laying modes were calculated quantificationally.Calculation result shows that the life cycle cost of line on the ground is 7.216 billion yuan according to traditional life cycle cost method,and it is lowest.The generalized life cycle cost of underground line is 17.345 billion yuan according to generalized life cycle cost method,the total cost is lowest,and the underground line is the best scheme.3 tabs,3 figs,15 refs.
