摘　　要：8A编组地下车站的车站规模相对于6B编组车站其长、宽、高都相对较大,地铁快线车站应层高加大引起站内公共区楼梯提升高度和平面长度增加,同时梯柱也相应增加,楼梯下方增设梯柱后占用站台层公共区面积,对站台层空间切割较为严重,影响站台空间通透,不利于站台乘客通行。针对此情况,有必要对快线地下车站公共区楼梯方案进行优化设计,提高车站空间利用率,力求达到功能合理,安全可靠,经济适用和技术先进的目的。The length,width and height of 8A marshalling underground station is greater than that of 6B marshalling underground station,with the public stair height and length increasing,the express station story is increasing and stair column is increasing too,which has severe impact upon the subway station space cutting,subway station space excavation and smooth transit as well.In light of the above mentioned conditions,it is necessary to carry out optimal design of the public staircase scheme of the city express,to improve the subway station space utilization ratio and to supply functional,safe,reliable,economic and advanced subway station staircase.
