徐连客运专线路桥方案比选

Scheme comparison between embankment and bridge of the railway Passenger Dedicated Line from Xuzhou to Lianyungang

徐连客专是在我国铁路网布局中具有重要作用,其不仅是我国八纵八横主干铁路网的重要组成部分,也是实现建设丝绸之路经济带的重要一环。该项目地处黄淮平原,地势较为平坦,为实现优化该方案的技术经济条件,首先对桥路方案基本影响因素进行了分析,其中关于工程造价从基本经济指标考虑做了定性分析,然后针对桥路相对优势不明显区域进行了定量分析,最终实现了整个方案在经济、技术条件上的全面优化。

The railway passenger dedicated line from Xu Zhou to Lianyungang is one of the most important railway lines of Chinese railway network. not only is it part of railway main lines, but also the key step of the construction of the silk road belt. This project located in huanghuai plan. Most terrain of it is smooth. To optimize the economic and technique conditions. First in the paper we make a analysis of the influence factors for the schemes. Of the influence factors the engineering cost is made a qualitative for the scheme. And then we choose some sections for a calculation of the cost of both the scheme. The result is that the costs of two schemes are close or the embankment scheme costs more than bridge scheme. Considering the local land resources, Environmental Protection the needs of local people＇s life, we recommend the bridge scheme.
