摘　　要：抗浮设计是埋地水池结构设计中非常重要的设计内容。自重不满足抗浮稳定要求的水池,会采取增加其它抗浮措施的方式辅助抗浮;抗浮构件会与主体结构产生相互作用,影响结构受力;设计中如何处理抗浮构件与主体结构的关系,又会对工程造价产生一定的影响。因此,结合福州地区部分工程项目,以桩基抗浮为例,分析水池底板与抗浮构件协同受力的特点,通过理论分析与Midas Gen有限元计算,着重讨论不同桩刚度对桩和底板受力计算的影响。分析表明,抗浮设计中,考虑抗浮桩与底板的协同受力是必要的。Anti-floating design is a very important content of buried pool structural design.Pools whose self weight does not meet the requirements for anti-floating stability will be assisted by adding other anti-floating measures.Anti-floating components will interact with the main structure,affecting the structural stress.How to handle the relationship between anti-floating components and the main structure in design will also have a certain impact on the engineering cost.This article combines some engineering projects in Fuzhou area and takes anti-floating piles as an example to analyze the characteristics of the cooperative working between the bottom plate of the pool and anti-floating components.Through theoretical analysis and Midas Gen finite element calculation,the influence of different pile stiffness on the force calculation of the pile and bottom plate is emphasized.Analysis shows that it is necessary to consider the cooperative working between the anti-floating piles and the bottom plate in the anti-floating design.
