摘　　要：不同站台宽度、柱网形式对地铁车站土建造价有重大影响。选取典型的地铁车站形式,对其结构内力及造价进行对比分析;对不同站台宽度的单柱及双柱车站内力分析其弯矩规律,并对比分析不同柱网形式下车站的弯矩变化规律。根据对比分析,11 m站台宽度的单柱车站及双柱车站的结构内力较合理,造价较低。对比分析的结论可为地铁车站方案决策提供参考。The differences in the width of the platform and the column form have great impact on the civil construction cost of the subway station. The internal force and the cost of the typical subway stations are analyzed and the bending moment distributions of different station platform widths with single column and double column are identified. And the change laws of bending moment with different column forms are discussed. The comparison shows that the internal forces of 11 m width platform with single column and double column are more reasonably distributed with relatively low cost. The conclusion can provide reference for determining the subway station scheme.
