摘　　要：刚性楼板假定在带来计算简化的同时也带来了许多问题,对于具体工程的结构设计选择合理的楼板刚度假定十分重要。针对某明挖车站的中板结构,分别选择PKPM/SATWE和MIDAS/CIVIL进行建模分析,对建模原理和计算结果进行了比较分析,给出了设计时模型选择的建议。The assumption of rigid floor brings the simplification of structural calculation as well as many problems, so it＇ s very important to choose a reasonable assumption of floor stiffness for structural design. This paper selects PKPM/SATWE and MIDAS/CIVIL to set up the analysis model, and makes a comparative analysis on the modeling theory and calculation results, and provides some suggestions on model selection for design,which can be used to direct the similar structure design.
