摘  要：
地铁换乘车站设计中,以平面模型计算结构内力并不能准确反映出车站受力真实形态,且列车荷载在结构受力中的影响并不能忽略,需将列车移动荷载联合车站使用工况共同考虑。本文通过采用midas civil有限元软件针对呼市地铁同期实施的换乘站进行研究,分别分析左线、右线、双线同时进站工况,研究梁、板内力分布特点,联合使用工况对车站进行配筋设计。结果表明,单线进站时车站受力最为不利,弯矩最大值集中于换乘节点接口处,靠近柱端弯矩较大。联合使用工况配筋结果,换乘节点处梁、板截面可以优化,优化量为39%左右,节省了车站造价。

摘  要：
In the design of subway transfer station, the calculation of the internal force of the structure by plane model cannot accurately reflect the true form of the station stress, and the influence of train load on the structure stress cannot be ignored,so the use of the train moving load in the station should be considered together. In this paper, midas civil finite element software is used to study the transfer station of Hohhot Metro at the same time. Left line, right line and double line are analyzed respectively. The distribution characteristics of internal forces in beams and slabs are studied. Reinforcement design is carried out under combined operation conditions. The result shows when a single line enters the station, the force is most unfavorable, and the maximum bending moment is concentrated at the interface of the transfer node, and the bending moment is larger near the column end. The result of joint use of reinforcement can optimize the section of the beam and plate of the interchange joint, and the optimized quantity is about 39%, saving the station cost.
