摘    要:采用反应位移法对某软土地区地铁车站标准段框架结构进行地震作用计算,分析计算结果表明,6度软土地区结构各构件截面尺寸及配筋均由标准荷载组合作用下的裂缝控制,地震作用工况不起控制作用;地震作用工况下柱端弯矩有明显增大的情况,应严格控制柱的轴压比;在结构薄弱部位需加强结构抗震构造措施。

关 键 词:地铁车站  地震作用  反应位移法

Abstract:The method of response displacement is used to calculate the seismic action of the standard section of subway station in a soft soil area,the calculation result suggests that the section dimension and reinforcement of component are controlled by crack under the standard combination on soft soil area in 6-degree area,the seismic action can't control the working conditions.Under the condition of earthquake action,the bending moment of the column end is obviously increased,and the axial compression ratio of the column should be strictly controlled.The structural anti-seismic construction measures should be strengthened in the weak part of the structure.
Keywords:subway station  earthquake action  response displacement method
