摘要
潍坊跨座式单轨1号线在市区火车站附近与既有铁路交叉,周边建筑密集、地下人防工程众多,且通道内分布有多条铁路线,如何处理好复杂城市环境下单轨线路和铁路交叉关系成为设计的重点和难点。为解决这一问题,采用调查、定性分析、定量分析和经验总结等研究方法,通过调查影响线路走向和交叉方案设置的控制因素,研究4种线路走向方案;经定性比选分析,对可行的沿青年路方案和沿白浪河西岸方案进行深化研究;通过线路平、纵断面设计,结合经验总结分析,确定采用沿青年路方案。之后对单轨上跨、下穿铁路方案,从工程情况、对铁路运营安全影响、对城市景观影响、对道路交通影响、工程投资等多方面进行定性、定量综合比选分析,并对施工工法、工期等方面进行可行性研究,最终推荐沿青年路西侧上跨铁路方案。
Weifang Straddle Monorail Line 1 crosses the existing railway near the railway station in the urban area.There are dense surrounding buildings,numerous underground civil air defense projects,and multiple railway lines along the monorail passage.The way to deal with the intersecting relationship between monorail line and railways in a complex urban environment has become a key point in the design.In order to solve this problem,this paper adopted research methods including survey method,qualitative analysis method,quantitative analysis method and experience summary method.Through investigating the controlling factors that affect the route and grade separation,four route schemes were studied.After qualitative comparison and analysis,the route scheme along Qingnian Road and the route scheme along the west bank of Bailang River were selected and included in the railway grade separation project to further deepen the study.Moreover,through the horizontal and vertical section design of the line,combined with the experience summary method,the route scheme along the Qingnian road was selected.Furthermore,for the intersecting scheme of the monorail and existing railways,comprehensive comparison and analysis of qualitative and quantitative were done,which included the influence on railway operation safety,urban landscape,road traffic,project investment,etc.Finally,feasibility studies on construction methods and duration were made,and the up-crossing railway scheme on the west side of Qingnian road was recommended.
