| Expansion of railway electrification project design and implementation, can fundamentally solve the low line transportation technology standard, delivery speed slow, lack of capacity, heavy task, large series of problems such as pollution. For speeding up to drive along the region’s economic and social developing, and promote the transportation management modernization of ji-tong railway group company, the project on schedule implementation has a very realistic and far-reaching significance.For proposed expansion of railway electrification project, need to carefully design the corresponding technical and economic evaluation. This is, after all, two very important content of the early stage of the project feasibility study, engineering is an important part of the final feasibility study report. According to the state and industry engineering, economic evaluation methods and parameters of design standard and requirement, this paper sets revamping/expansion of railway electrification project, on the premise of the feasible design technique, detailed has carried out its corresponding economic evaluation work, aims at providing a set of railway (group) co., LTD for scientific project investment decision-making to provide the necessary reference.This paper first summarizes the expansion of railway electrification engineering background, and then introduces the scheme design of the main body of engineering technology, under the premise that ensure that the technology is feasible, to further expand the overall analysis of the economic evaluation work, has, in turn, estimate the important basis of the engineering data, such as investment, cost, revenue, business tax and additional and profit, etc., on this basis, then carried out for the project financial evaluation and national economic evaluation. The final evaluation results show that the expansion of railway electrification project has good financial feasibility and economic benefits, should strive for an early on, and effective early, the paper also gives other corresponding suggestions. |
