［摘要］近几年地下水位上升导致建筑结构破坏时有发生。针对上述问题，对抗浮水位的获取途径、抗浮设计内容和措施等进行了阐述、总结，并详细介绍了抗拔桩与抗拔锚杆的布置原则，最后对三个工程实例进行了抗浮设计。得出如下结论：在进行防水板厚度计算时，不应考虑抗拔锚杆的支点作用；当管廊横截面宽度超过6m时，建议不要单纯采用底板外挑抗浮措施。从经济性上考虑，抗拔桩应尽量选择桩径较小的桩。

Abstract:In recent years, the rise of underground water level has leaded to the failure of building structures from time to time. With regard to the above problem, the approach of obtaining anti-floating water level, anti-floating design content and measures were elaborated and summarized, and the arrangement principles of uplift piles and uplift anchors were introduced in detail. At last, anti-floating designs have been made for three engineering projects. The following conclusions are drawn that when calculating the thickness of the waterproof plate, the fulcrum function of uplift anchor should not be considered; when the cross-sectional width of the pipe gallery exceeds 6m, it is recommended not to simply adopt the anti-floating measures by means of overlanging bottom plate. Considering the economy, the pile with smaller diameter should be chosen as far as possible for the uplift pile.
