摘　　要：受制于建成环境,早期设计不足等问题,地铁既有站点往往难以承载新建换乘线路开通后的大量客流。以中山八站为例,提出一种基于不同客流场景的客流组织方案抉择方法。首先,通过社会力仿真模型软件定量分析新建地铁换乘线路对既有站点的客流影响;其次,基于预测客流情况对不同客流组织方案的客流承载力进行演算,从而验证了当前设计方案的合理性;最后,依据未来不同的实际运营客流量,进行站台承载力极值验算,并以此进行方案抉择论证。结果表明:当未来实际客流为预测客流的0.8倍及以下时,建议选择通道式换乘方案来提升换乘效率;未来实际客流超过预测客流的0.8倍且低于1.35倍时,建议选择组合式换乘方案,进而缓解站点承载压力;当超过1.35倍及以上时,建议设置一定的运营手段缓解承载压力。文中提出的决策方法可实现在满足既有站点安全性前提下提升换乘效率的要求,从而为实现地铁高峰时期站台的高效安全运营提供有效参考。Limited by the built environment and early design deficiencies,existing subway stations often face the challenge of accommodating the substantial passenger flow resulting from the introduction of new transfer lines.Taking Zhongshanba Station as a study case,this paper presents an approach to selecting passenger flow organization schemes based on different flow scenarios.Firstly,a quantitative analysis of the impact of the new transfer line on passenger flow at the existing station was conducted using a social force simulation model.Secondly,this paper examined the carrying capacity of different passenger flow organization schemes according to passenger flow forecast,thus validating the current design??s feasibility.Finally,this paper conducted the extreme value calculation of platform bearing capacity under different operational passenger flows,and carried out scheme selection and demonstration.Results indicated that when future actual passenger flow is 0.8 times the passenger flow forecast,a channel transfer scheme is recommended,which will largely improve the transfer efficiency.When future actual passenger flow is 0.8~1.35 times the forecast,the combined station hall transfer scheme is advised to alleviate station load pressure.For passenger flows 1.35 times or greater than the forecast,operational strategies should be implemented to relieve load pressure.The decision-making method proposed in this paper seeks to maximize transfer efficiency while ensuring the safety of existing stations,providing a reference for efficient and safe platform operation during subway peak hours.
