Abstract
With the development of high speed railway construction in the Midwest of China, it is essential to select reasonable targeted speed inareas with complex terrain for engineering investment, transportation quality and the significance of the railway network.Xi
'an-Ankang High-speed Railway is part of Xi'an-Chongqing High-speed Railway, and it passes through Qinba Mountain area.Therefore, the targeted speed of Xi'an-Chongqing High-speed Railway is studied first.On the basis of analyzing passenger characteristics and needed travelling time, the scheme of 350 km/h which has the highest economic efficiency is proposed following comprehensive analysis and according to its functional position and the coordination with the whole railway network.Then, the targeted speed of Xi'an-Ankang High-speed Railway is studied in detail, and the scheme of350 km/h identical to that of Xi'an-Chongqing High-speed Railway is recommended.The research conclusions meet the transport demand of Xi'an-Ankang High-speed Railway and coordinate with the regional railway network with moderate engineering scale and investment level.Meanwhile, the scheme can bring about excellent comprehensive benefit and provide technical support for the standard selection of Xi'an-Chongqing High-speed Railway.关键词
