无砟轨道造价指标分析

无砟轨道能满足高速行车的技术要求,已成为客运专线普遍采用的轨道形式,国内高速铁路在经过近几年来的不断摸索和创新后,无砟轨道技术日趋成熟。针对我国铁路已经应用的几种无砟轨道类型,从造价指标的角度,结合轨道结构、施工便利程度、工程量等因素,为无砟轨道类型的比选提供参考依据。

Analysis of the Indices of the Engineering Cost of Ballastless Tracks

Ballastless tracks can satisfy the technique requirements of the high-speed trains,and thus have been widely adopted by the passenger dedicated lines.Centered with the types of the ballastless tracks applied in the railways of China,this paper from the perspective of the engineering cost proposes the reference for selecting the type of ballastless tracks by combining the track structure,the construction convenience,and the engineering quantity.
