合肥枢纽商合杭铁路绕行原因分析及方案研究

Cause Analysis and Scheme Study on Roundabout ofShangqiu-Hefei-Hangzhou Railway at Hefei Terminal

合肥枢纽衔接既有合蚌、合福、商合杭及规划沿江高速铁路等多条线路,形成大型放射状枢纽。受合肥北城站型影响,商合杭铁路开通后需在合肥北城站转线至合福铁路,绕行经合肥南站、巢湖东站后回归商合杭本线,引起运输时分和距离增加。针对这一问题,本文通过梳理合肥枢纽客站分工和点线能力,详细分析商合杭铁路绕行原因,从提升通道能力、增设联络线等方面提出建议,解决商合杭铁路绕行合肥枢纽并有效缓解阜阳至杭州方向运输组织不顺畅的问题。

Hefei Hub,which connects many railways including existing Hefei-Bengbu Railway,Hefei-Fuzhou Railway,Shangqiu-Hefei-Hangzhou Railway,and the planned high-speed railway along the Yangtze River,is a large radial hub.Due to the layout of Hefei Beicheng Railway Station,after Shangqiu-Hefei-Hangzhou Railway is put into operation,a train coming from this railway needs to transfer to Hefei-Fuzhou Railway at Hefei Beicheng Station,makes a roundabout by passing Hefei South Railway Station and Chaohu East Railway Station successively,and finally returns to Shangqiu-Hefei-Hangzhou Railway,which causes an increase of time and distance.To solve this problem,this paper reviews the function distribution and service capabilities of the passenger stations of Hefei Hub,analyzes in detail the reasons for the roundabout of Shangqiu-Hefei-Hangzhou Railway,and puts forward some suggestions including improving the passage capacity and adding connecting lines,to solve this roundabout and effectively alleviate the unsmooth transport organization from Fuyang to Hangzhou.
