摘要
针对预应力混凝土箱型结构的受力特点,采用MIDAS进行实体单元的模型分析,找出腹板裂缝产生的主要原因,提出改善腹板受力的措施,为同类型结构设计提供参考。
In view of the mechanical characteristics of the structure of prestressed concrete box-type, this paper analyzes the entity unit model by MIDAS, investigates the main reason for the web of cracks, and provides some measures to improve the force applied on the web, which may serve as reference for the similar bridge design.
