摘　　要：本文结合工程实例对整体抗浮布置锚杆方式下的底板进行了受力分析,分析了锚杆刚度、底板刚度对锚杆受力的影响,提出了根据锚杆受力情况确定底板厚度的方法。根据考虑活荷载组合下与折减水压情况下底板受力情况,提出了通过将锚杆拉力折算为均布荷载,在水浮力中输入中予以折减的底板设计方法,以供类似工程参考。Combining with engineering examples, the stress analysis was carried out on the bottom slab of the whole decorate anti - floating anchor rod way, ana- lyzed the influence of the anchor rod stiffness and bottom slab stiffness to anchor rod stress ,put forward method of determine the thickness of bottom slab according to the anchor red stress. According to bottom slab stress of consider live load combinations and reduction water stress,by the anchor rod tension converted into distributed load, the bottom slab design method of considering water buoyant force reduction is put forward, in order to provide the reference for the similar engineering.

关 键 词：底板 锚杆 弹簧刚度 恒荷载 水浮力
