［摘要］某擋土結(jié)構(gòu)南側(cè)為下沉廣場，其余三面均承受土側(cè)壓力。借助南側(cè)大底盤地下室提供側(cè)向約束，解決了結(jié)構(gòu)的整體抗傾覆問題。將樓板視作墻體彈簧支座，優(yōu)化了墻體配筋。建立結(jié)構(gòu)的有限元模型，獲取了構(gòu)件內(nèi)力并進(jìn)行設(shè)計(jì)。設(shè)計(jì)案例可為相關(guān)工程設(shè)計(jì)提供參考。

Abstract： 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.
Keywords： retaining wall; single-span structure; finite element calculation
