摘要
芜湖市轨道交通是国内首次采用中运量跨座式单轨系统建设的轨道交通骨干线,建设实施的1号线、2号线一期工程共设有34座高架车站,其中28座设于路中。车站选型的合理性、平面布局的便捷性、建筑形态的美观性直接影响其运行效率和城市形象。随着社会的发展与进步,人们对交通建筑功能提升的需求、高架系统景观协调性的要求和对地域文化性表达提出了更高要求,因此,路中高架站的轻量化研究至关重要。通过对车站使用功能、站台利用率、区间景观效果、结构受力分析、与道路适应性、设备用房布设条件等多方面分析与研究,芜湖市轨道交通高架站选择侧式站台作为车站标准站型。提出了根据车站所处不同区位的具体属性特征,进行站点周边规划与景观融合的一体化规划设计;以标准站型为研究对象开展平面布局优化与空间高效利用技术的研究;针对工程穿越芜湖市老城区时,路中绿化带宽度仅为3 m,采用传统的钢筋混凝土结构型式难以满足实际设站条件的工程实际,研发了跨座式单轨新型结构体系成套关键技术。研究成果对芜湖市轨道交通工程路中高架车站的选型、平面布局、立面设计、空间利用、结构体系、抗震设计及节点设计进行了全面介绍,对一系列关键技术及创新进行了系统总结,独柱钢-混组合结构为道路条件受限的城市轨道交通路中高架车站探索了一条新的实践之路。
Wuhu rail transit is the first rail transit backbone line to be constructed by using the medium-volume straddle monorail system in China.The Phase I project of Line 1 and Line 2 constructed and implemented has 34 elevated stations,of which 28 are located in the middle of the road.The rationality of station type selection,the convenience of plane layout and the outlook of buildings directly affect its operation efficiency and city image.With the development of society and the requirements of the coordination of the elevated system landscape,higher requirements are put forward for the expression of regional culture,and the lightweight research of elevated stations becomes very important.Through the analysis and research of the station function,platform utilization rate,section landscape effect,structural stress analysis,road adaptability,equipment room layout conditions and other aspects,Wuhu rail transit elevated station selects side platform as the standard station type.According to the specific attribute characteristics of different station locations,the paper proposes integrated planning and design of surrounding area and landscape of the station.Taking the standard station type as the research object,the research on plane layout optimization and space efficient utilization technology is carried out.In view of the fact that the green belt in the middle of the road is only 3 m wide,where the project crosses the old urban area of Wuhu City,and the traditional reinforced concrete structure can hardly meet the actual conditions for station setting,a set of key technologies for the new straddle-type monorail structure system are developed.The research results comprehensively illustrate the type selection,plane layout,elevation design,space utilization,structural system,seismic design and node design of the elevated station in the middle of the road of Wuhu Rail Transit Project,and systematically summarize a series of key technologies and innovations.The single-column steel-concrete composite structure studied in the
