地铁车站站台宽度设计再思考

通过实地调研各地客流较大的地铁车站,分析站台客流分布以及运行特征,同时结合笔者多年从事轨道交通建筑设计经验以及对现行《地铁设计规范》(GB50157-2003)的分析理解,指出现行规范中关于车站站台宽度理论计算与实际运营需求存在的问题、产生的原因,根据站台客流分布以及疏散特征提出相关解决方案,为今后的地铁设计提供新的思路。

Reconsideration on How to Design the Width of Station Platform of Metro

Through on-site investigation and research about metro stations with larger passenger flows all over the country,this study analyzed the passenger flow distribution and operation characteristics at station platform of metro. Simultaneously,combined with the authors' many years of work experience on rail transit architecture design,as well as combined with the analysis and comprehension on the current design code,Code for Metro Design( GB50157- 2003),this study pointed out the conflict problem between the theoretical calculation stipulated in the current design code and the actual operation demand about the widths of station platform,and analyzed the reasons of the conflict problem. Finally,this study put forward relevant solutions based on passenger flow distribution and evacuation characteristics at station platform,providing a new idea for metro design in future.
