地下高铁站规模及站型研究

Research on the Scale and Type of Underground High-speed Railway Station

研究目的:地下高铁站数量逐年增加,此类车站用地紧张、施工风险大、投资高,以铁路中间站为主,其站型和规模的确定对车站使用功能和投资效益极为重要。分析不同站型和规模地下高铁站的车站通过能力、到发线数目对车站功能的适应性、地下站站型不同条件下的适用性,研究在满足地下站作业类型、符合车站远期办理作业数量的前提下,地下高铁站不同规模及站型的特点,解决地下高铁站站型选择问题。研究结论:(1)岛式站和侧式站虽然规模和投资小,但不具备越行等条件,多用于轨道交通,不适用国铁线路;(2)两台夹四线站型规模和投资较小,适宜每天办理列车对数小于34对,且以停站通过列车为主的车站;(3)双岛四线站型适宜远期每天办理列车作业对数在34~69对之间的车站,可适应于各作业类型均占一定比例的地下中间站;(4)两台六线车站占地面积和工程投资大,径路相对灵活,适用于办理列车折返、始发终到、越行等作业类型多,每天办理列车作业数量69~104对的车站;(5)当车站办理列车对数大于104对或有多线引入中间车站时,到发线数目和站型选择可参照以上数据;(6)本研究对处于设计阶段的地下中心城区高铁站、机场高铁站、景区高铁站规模和站型的确定具有参考和借鉴意义。

Research purposes: The number of underground high-speed railway stations is increasing year by year. Such stations are limited in land use, with high construction risks and high investment. They are mainly intermediate railway stations and the determination of station type and scale is very important to the station function and investment benefit. Analysis of different type and size of the underground station passing capacity, number of arrival and departure lines on the station function of adaptability, the applicability of the different model. On the premise of satisfying the operation types of underground stations and conforming to the long-term operation quantity of stations, the characteristics of different sizes and station types of underground high-speed railway stations are studied to solve the problem of station type selection of underground high-speed railway stations.Research conclusions:(1)The island stations and side stations are small in scale and investment, but they do not have the crossing lines, so they are mostly used for rail transit.(2)The two-platform and four-line stations can handle trains less than 34 pairs every day, and they are cheaper and used for stops and passes trains mainly.(3)The double-island four-line stations can handle starting, arriving, passing and passenger operations between 34 and 69 pairs every day, it’s suitable for the stations with a certain proportion of each operation type.(4)The two-platform and six-line stations cover a huge area and larger investment, the route is relatively flexible and can handle starting, arriving, passing and passenger operations with 69~104 pairs trains every day.(5)When the number of train pairs at the station is greater than 104 or multiple lines are introduced into the intermediate station, the number of arriving and departing lines, station types choice can refer to the above data.(6)This research has reference and guiding significance for the determination of the scale and type of underground central urban high-speed railway station, airport high-speed railway station and scenic high-speed railway station in the design stage.
