高铁无碴轨道支承层滑模施工经济性分析

Analysis of economy to slipping work about ballastless track HBL

通过实地研究考查,分别对高铁水硬性支承层滑模施工与支模施工成本进行了各自对比性分析。并取采用两种施工方法的武广客运专线标段,取同一时期铺筑相等数量的水硬性支承层作为基础进行分析对比,结果表明目前国内滑模施工技术引起的施工成本比起支模施工优势性不大,同时提出了造成这一结果的可能性原因。

Through studies on-site,we did a comparative costing analysis about slip-form pavement and manual work of high railway HBL re-spectively.And selected Wuhan-Guangzhou passenger line tenders where obtained using two kinds of construction methods,taking the same amount of paved HBL during the same period as the basis for analysis.The results showed that the current domestic construction cost of slip-form pavement is not prominent enough to manual work,at the same time,we raised the possible reasons for this outcome.
