摘　　要：叠层升板是由传统的逐层提升改为一次提升两块板的提升方法。利用自主开发的基于ANSYS有限元程序的升板模拟仿真程序并以4层升板结构为例,对叠层升板过程中框架结构的屈曲载荷、柱的轴力、柱底弯矩、混凝土板的应力分布等进行分析并与传统升板进行比较。结果表明,在群柱稳定性得以保证的前提下,叠层升板在优化施工工序、降低工程造价、缩短施工周期等方面具有显著的优势和良好的经济效益。The laminated lift-slab method means to lift two slabs one time upgraded from the traditional layer by layer lifting. Using a four-storey lift slab construction as an example and through the self-developed lift slab simulation program based on the ANSYS finite element program, the frame structure’s buckling load, column axial force, column bottom moment and stress distribution of the concrete slab during a laminated lift slab construction are analyzed and compared with the traditional ways. The results show when the stability of the grouped columns can be guaranteed, the laminated lift slab construction has the significant advantages in optimizing the construction process, reducing the project cost and shortening the construction period etc.
