深圳市某大型地铁车站盖挖逆作法设计探讨

Structure design of a metro station in Shenzhen using covered top-down construction method

  • 摘要: 对一个采用盖挖逆作法的地铁车站进行了施工全过程的模拟计算,较好地反映了使用阶段的结构受力对施工阶段受力的继承关系,从而得到较为准确的内力和变形,并对侧向土压力的选取及不对称结构支撑刚度的修正提出建议,同时计算也表明,采取墙背土压力随开挖过程而变化的方法更合理,对类似设计具有一定参考价值。

     

    Abstract: The whole construction process of a metro station is simulated by using the covered top-down construction method. The calculated results better reflect the inheritance relationship of the structural response between the construction stage and the servile stage, resulting in more accurate internal force and deformation. Besides, some new methods are also proposed to choose the lateral earth pressure and to modify the brace stiffness of the asymmetric structure. It is more reasonable to make the lateral earth pressure vary with the excavation process. It may provide reference for the design of the similar projects.
