嘉善大道公铁共线段快速化改造总体方案研究

Research on Overall Scheme for Rapidization Reconstruction of Combined Road-Rail Section of Jiashan Avenue

摘要:

嘉善县嘉善大道总体方案设计时，针对其与规划市域铁路共线段3.6 km范围内的快速化需求，提出高架合建、隧道分建、高架分建、连续下立交等4种总体方案比选，从铁路建设要求、公铁复合通道间相互影响、环境景观、线形指标、用地等多维度的系统对比分析择优确定了快速化方案，能够满足公铁共线约束条件下的建设要求，同时重要节点结合主线功能、匝道布设、铁路、用地条件等限制因素进行了对比取舍，可为类似公铁共线的快速化改造道路设计提供借鉴。

Abstract:

In the design of the overall scheme for Jiaxing Avenue in Jiashan County, in response to the demand for rapidization within a 3.6 km range of the section shared with the planned urban railway, four overall schemes of elevated co-construction, tunnel separation, elevated separation and continuous underpass are proposed and compared. The rapidization scheme is optimized and determined through a systematic comparative analysis of multiple dimensions, such as railway construction requirements, mutual influence between rail-road composite channels, environmental landscape, alignment indicators and land use, which can meet the construction requirements under the constraints of combined rail and road lines. Meanwhile, the important nodes are compared and selected in combination with the main line function, ramp layout, railway, land use conditions and other restrictive factors, which can provide references for the design of rapidization reconstruction of similar roads of combined rail and road lines.
