摘要
标准地铁车站在国内地铁设计中较为常见,而倒厅地铁车站则比较少见,尤其是多线换乘的综合交通枢纽倒厅地铁车站更为少见。为解决倒厅地铁车站在设计中存在的难点,结合西安城际铁路机场线与西安地铁4号线换乘的综合交通枢纽倒厅地铁车站设计实例,通过对倒厅地铁车站的设计方法及思路进行分析与归纳总结,建议在类似的倒厅地铁车站设计时仔细分析各输入条件及控制因素,重点把握倒厅地铁车站的防火分区划分及消防疏散设计,尽量将非常规的疏散方式优化为常规的疏散方式。
Standard metro stations are common,whereas inverted-hall metro stations are uncommon in China,particularly in a comprehensive transportation hub with multiple lines.To overcome the difficulties in the design of inverted-hall metro stations,a case study is conducted on the design of an inverted-hall metro station of a comprehensive transportation hub for the interchange between Xi′an intercity railway airport line and metro line 4.The design methods and concepts of the inverted-hall metro station are thoroughly examined and summarized.It is suggested that the input conditions and control factors should be carefully analyzed in the design of similar inverted-hall metro stations,with special consideration to the fire compartment division and fire evacuation design.Moreover,the unconventional evacuation mode should be optimized into the conventional evacuation mode,resulting in a more rational metro station design scheme.
