摘　　要：本文讨论了以地下多层框架为代表的钢筋混凝土结构在设计中所经常遇到的问题,即对地下复杂结构采取有限元计算时,如何选择合适的建模方法对结构进行模拟。此外,对常用的有限元计算方法(板单元模型和实体单元模型)的优缺点和计算误差进行比较,作为今后类似计算的参考数据。This paper discussed frequently encountered problems of indications represented by underground multilayer framework in the reinforced concrete structure in the design, that is how to choose the appropriate modeling methods for simulating structure in the finite element calculation of underground complex structure. In addition, the advantages, disadvantages and calculation error of the commonly used finite element method （plate unit and entity unit model） model were compared as a future reference data of similar calculation.
