某单跨挡土结构设计

Structural design of a single-span resisting structure

某挡土结构南侧为下沉广场,其余三面均承受土侧压力。借助南侧大底盘地下室提供侧向约束,解决了结构的整体抗倾覆问题。将楼板视作墙体弹簧支座,优化了墙体配筋。建立结构的有限元模型,获取了构件内力并进行设计。设计案例可为相关工程设计提供参考。

The resisting structure is facing the sunken plaza on the southern side,while bearing earth pressure on the other sides. Taking the southern basement structure as support,the anti-overturn stability of the single-span resisting structure was solved to meet the standard need. The slab was taken as the spring support of the retaining wall,Thus,the reinforcement of the wall was optimized. Finite element model of the structure was set up,and the member forces were obtained to design. This design case may be a reference for similar projects.
