摘　　要：针对我国目前因在设计混凝土结构D区时尚无完善的理论依据,进而造成了很多混凝土D区开裂等工程问题,引入拉-压杆理论进行混凝土D区的配筋设计,提出拉-压杆模型的选取原则,并以一深梁为例按照拉-压杆理论进行了设计,总结出拉-压杆理论的设计步骤,可为类似工程提供参考。For there is no perfect design theory for concrete structure disturbed field to apply, a lot of concrete disturbed field crack accidents were produced. So STM （strut-and-tie method） is proposed to be used for the design of concrete disturbed field. The selecting principle of STM is proposed. A deep beam was designed based on STM and designing steps were summarized. It can be referenced for similar projects.
