摘要:
目的：现行设计规范中，常以站台宽度规模来评判城市轨道交通车站的总体规模，但由于所处环境的复杂性，该指标已无法真实反映车站规模的整体情况，因此需对城市轨道交通车站建设规模的影响因素进行分析。方法：建立了车站规模数据分析模型，选取车站面积比例构成、车型、配线设置、车站埋深等车站规模影响因素进行分析，并计算了其中2个因素的影响占比。结果及结论：广州6A(6节编组、A型车)降压标准车站站厅层的公共区占该站厅层的面积比例约为30%，设备管理用房占该站厅层的面积比例约为70%。在设备管理用房中，环控设备用房与风道占比较高，约占站厅层设备管理用房的50%；广州地铁标准参考图6A和6B(6节编组、B型车)车站的面积比例构成情况基本一致，不同车型的车站对车站总规模的影响占比仅为7%；配线设置对于车站建设规模的影响较大，在设计初期应重点关注线路配线的系统功能，合理选择配线方案；在相同系统功能与相同服务功能的条件下，车站埋深越大，车站建设总规模也越大，不同车站埋深对车站总规模的影响占比为23%。

Objective: In the current design specifications, the overall scale of urban rail transit stations is judged by platform width scale. However, due to the complexity of surrounding environment, this indicator no longer reflects the actual conditions of station overall scale. Therefore, it is necessary to carry out analysis of urban rail transit station construction scale influencing factors.Method: A data analysis model for station scale is established. Station scale influencing factors such as station area proportion composition, train type, auxiliary line setting, and station buried depth are selected for the analysis, and the impact proportions of two among these factors are calculated.Result & Conclusion: In Guangzhou, the proportion of public areas on the concourse level of a 6A (6car formation, Atype vehicle) step down standard station is approximately 30%, while the proportion of equipment management rooms accounts for 70%. Among the equipment management rooms, the proportion of environmental control equipment rooms and ducts is relatively high, accounting for about 50% of the concourse level equipment management rooms. The area proportion composition conditions in standard reference diagrams for Guangzhou Metro 6A and 6B (6car formation, Btype vehicle) stations is similar, and the impact of different train types on the overall station scale takes up only 7%. The auxiliary line setting has a significant impact on station construction scale, and attention should be paid to the system functionality of auxiliary lines at the initial design phase, with a reasonable selection of auxiliary line schemes. Under the same conditions of system functionality and service functions, stations with greater buried depth have a larger overall construction scale, with the factor of different buried depths accounting for 23% impact on the overall station scale.
