摘要

研究目的：根据宁西铁路(南合段)现状情况、所处地形、地质条件等，对该线功能定位、运输需求、与相邻线路匹配等因素进行分析，并经多方案技术经济比选，提出宁西铁路(南合段)扩能改造速度目标值的推荐意见。

研究结论：鉴于宁西沿线地形平坦，既有线区间最小曲线半径均在1600 m及以上(条件较好)，但也为了避免既有线大拆大改、节省投资，既有线应按提速至160 km／h的速度目标值设计；新增二线，根据宁西线“以货为主、兼顾客运”的功能定位，及为了与既有线及邻线路能较好地匹配，其速度目标值也应采用160 km／h。

Abstract

Research purposes: According to the current situations，topographic conditions and geological conditions along the railway from Nanjing to Xihn(Nanyang—Hefei district)，the recommended speed target value for upgrading Nanjing—Xi’an Railway is offered after making analyses of the railway functions．traffic demands and matching relation with neighbour railway and comparing many schemes in technology and economy．

Research conclusions: The speed target value for upgrading Nanjing—Xi’an Railway increases to 160 km／h because the topographty along the railway is flat，the minimum track curve radius is 1 600 m or above．In addition，dong so is to avoid bigger dismantling and changing for the railway and save the investment．The speed target value of 1 60 km/h is also designed for the additional second track of the railway to well match the existing track and neighbour railway according to the functional orientation of the railway that mainly undertakes freight transportation and simultaneously undertakes passenger transportation．
