以地铁地下车站换乘形式的合理性和可实施性为研究目的，以换乘车站的换乘模式为研究对象，从车站功能（包括换乘功能）、客流组织、车站和区间的工程实施难易程度、综合投资、运营安全以及社会效益等方面论述和分析平行换乘模式下的双岛四线式换乘和上下叠岛式换乘，并介绍交汇换乘模式下的“十”、“T”、“L”形换乘、通道换乘，以及组合换乘模式的主要特点及适用条件，并通过列举国内工程实例进行说明补充，总结地铁地下车站换乘形式合理选择和设计中的要点，以及如何减少对安全运营的影响，并对今后地铁换乘设计提出一些有价值的意见及建议。

The passenger transfer modes of underground Metro stations are summarized as follows: 1) parallel transfer modes, including dualisland fourtrack transfer mode and verticaldirection island transfer mode; 2) cross transfer modes, including “+”shaped transfer mode, “T”shaped transfer mode, “L”shaped transfer mode and passage transfer mode; 3) combined transfer mode. The functions, passenger organizations, construction difficulty degrees, comprehensive investment, operation safety and social significance, as well as case histories, of each transfer mode mentioned above are presented. The key points in the passenger transfer mode selection and design of underground Metro stations are proposed and some advices are made on the operation safety and transfer design of future Metro works. 
