Feasibility Study On The Third Phase Southern Extension Construction Project Of Subway 8 In Beijing

Urban rail transport as a green, energy-saving, environmentally friendly public transport has been gradually as an important means of solution to traffic congestion, improve the proportion of public transport and reduce car trips transportation in major cities. Rail transit investment projects are large public investment in infrastructure construction projects, which invest mainly in government finances, Feasibility study is very necessary, To improve the scientific of the investment decisions.This paper on the basis of the theory of feasibility study, Carry feasibility analysis on the third phase southern extension investment construction project of subway 8 in Beijing.In technical scheme.In the light of the characteristics of the project for existing lines in extension project, The research is focus on the technology solutions suitable for the current project and match the existing engineering, Research interface problem between each system of project with both engineering, Through contrast analysis feasible technical scheme is put forward. In investment estimation, estimated the investment of project according to the scope of engineering, And consider the cost by upgrade the existing engineering due to the extension line. In financial and economic cost-benefit analysis, Select reasonable parameters for financial cost benefit analysis, financial index analysis, uncertainty analysis.economic cost-benefit analysis report, analysis index, sensitivity analysis. In risk analysis, The risk analysis through the logic and thinkingrisk of identification risk estimation and risk evaluation.reach preliminary conclusions of feasible or unfeasible about project investment.
