摘　　要：地下建筑因其独特的空间位置,受到地下水浮力的显著影响,抗浮设计是保障结构安全的关键。本文基于地下建筑结构浮力失效机理,分析了地下水位、土层性质、结构自重及荷载分布等因素对抗浮稳定性的影响。在总结传统抗浮设计方法的基础上,重点探讨了新型抗浮技术及优化策略。通过分析场地水文地质、结构型式、材料性能、施工工艺等关键影响因素,提出了抗浮设计的针对性措施。结合某地下综合体工程案例,阐述了抗浮设计的技术难点及主要做法,为类似工程提供了有益参考。Due to its unique spatial location,underground buildings are significantly affected by the buoyancy of groundwater,and anti-floating design is the key to ensuring structural safety.Based on the failure mechanism of buoyancy in underground building structures,this article analyzes the influence of factors such as groundwater level,soil properties,structural self-weight,and load distribution on the buoyancy stability.On the basis of summarizing traditional anti-floating design methods,it focuses on exploring new anti-floating technologies and optimization strategies.Targeted measures for anti-floating design are proposed by analyzing key influencing factors such as hydrogeological conditions,structural types,material properties,and construction processes of the site.Combined with the engineering case of an underground complex project,this article elaborates on the technical difficulties and main methods of anti-floating design,providing useful references for similar projects.
