摘　　要：以中云客站旅客站房梁开洞问题为背景,比较了梁单元模型与实体单元模型优缺点,分析得出梁单元加实体单元组合模型比较合理,对梁单元与实体单元的连接处理采用了刚性连接方法,并通过模型验证此方法的合理性,最后进行了在预应力作用下梁的受力分析并得出结论。With the Zhongyun station hotel beam punch as background, the merits and drawbacks of beam unit model and solid unit model were compared. It obtained that the combined model by beam unit model and solid unit model was proper. The rigid connection form was adopted to beam unit and solid unit, its rationality was checked by model. At last, the force analysis under prestressed force was analyzed and conclusion was obtained.
