摘　　要：地铁车站换乘通道的长度对地铁客流组织、乘客出行具有重要的作用。针对地铁换乘站换乘通道长度合理性的问题,考虑乘客的差异性,研究了换乘通道长度对客流的影响机理;提出了地铁车站合理换乘通道长度的理论计算方法,并进行了仿真分析。通过对北京地铁崇文门和复兴门换乘站进行的实例研究,提出了换乘通道合理长度的优化建议。研究发现,地铁换乘通道长度与宽度共同决定了通道的客流集散效果,适当增加通道长度能有效缓解客流冲击;但随着地铁换乘通道长度的增加,长通道缓解客流对站台冲击的效果会减弱。所提出的建议可供地铁换乘车站设计作参考。The length of transfer passengeway at metro sta- tion plays an important role in passengers organization and travel. By referring to the rationality evaluation of transfer passageways＂ length, and fully considering the differences between passengers,the influencial mechanism of passenge- way length over passenger flow is studied, and a simulation analysis is conducted. Based on a case study of Beijing metro passageway between Chongwenmen Station and Fuxingmen Station, an optimum proposal is put forward. In this study, it is discovered that the length and width of metro passageway will decide the passenger flow distribution altogether, while extending the length of passengeway will alleviate the im- pact of passengers over metro platform, but the length must be controlled in a proper scope.
