摘要
我国正处于高速铁路建设的高潮之中,如何对高速铁路轨道结构的技术经济性进行科学、系统的评价,是值得研究的问题。通过综合考虑影响轨道应用效果的各种技术、经济因素,建立层次分析模型进行评价,最后得出高速铁路无砟轨道较有砟轨道的技术经济性更高的结论,为无砟轨道在我国高速铁路建设中的推广提供了依据。
High-speed railway construction is booming in China.Scientific and systematic evaluation for technical and economical efficiency of high-speed railway track structure is an issue to be studied.Through considering all technical and economic factors that are influencing the application of track,analytic hierarchy process model is established for evaluation.Finally it obtains the conclusion that high speed railway ballastless track has higher technical and economical efficiency than that of ballasted track,which provides basis for promotion of ballastless track in high-speed railway construction in our country.
