摘　　要：随着城市地铁线网客流快速增长,换乘站原始设计的客流及结构难以满足客流运动规律,很多换乘站出现客流堆积的情况,短时间超大客流对于运营造成较大安全隐患。依托广州地铁换乘车站实际客流数据,通过分析现有规范存在的问题,提出新的侧站台宽度计算模型,在新模型中考虑了站台上乘客的分布情况,并根据节点站(始发站、通过站)的特点,给出两种计算方法下人流密度ρ的取值建议,为计算车站的换乘能力提供依据,并为后续新线接入研究提供了理论支持。对始发站而言,人流密度建议取值为0.35~0.70 m^(2)/人,一般可考虑取0.45 m^(2)/人进行测算;对通过站而言,采取设计规范提供方法1(即同时考虑上下车乘客),候车区人均占地面积建议取值为0.5 m^(2)/人;采取设计规范提供方法2(即仅考虑上车乘客),则候车区人均占地面积建议取值1.0 m^(2)/人。With the rapid growth of the passenger flow of the urban subway network,the originally designed passenger flow and struc‐ture of the interchange station cannot meet the passenger flow movement law.Many interchange station have accumulated passenger flow,and the large passenger flow in a short period of time has caused great security risks for the operation.This article relies on the actual pas‐senger flow data of Guangzhou subway transfer stations,analyzes the problems existing in existing standards,proposes a new calculation model for side platform width,takes into account the distribution of passengers on the platform in the new model,and provides two calcula‐tion methods for pedestrian density based on the characteristics of node stations(originating and passing stations)r,the suggested value pro‐vides a basis for calculating the transfer capacity of stations and theoretical support for subsequent research on new line access.For the depar‐ture station,the recommended value for pedestrian density is 0.35~0.70 m2/person,and generally 0.45 m2/person can be considered for calcu‐lation;For passing stations,method one provided by design specifications(i.e.considering both boarding and alighting passengers)is adopt‐ed,and the recommended per capita land area of the waiting area is 0.5 m2/person;If the design specification is adopted to provide Method 2(i.e.only considering boarding passengers),the recommended per capita land area of the waiting area is 1.0 m2/person.
