［摘要］总结了各规范、文献关于抗浮锚杆承载力的计算规定，然后通过工程实例，建立文克尔地基-锚杆-底板共同工作模型，分析并总结了锚杆布置方式、刚度及底板厚度对锚杆及底板受力的影响规律，提出了抗浮锚杆拉力不均匀分布系数，通过该参数可对地下室抗浮锚杆布置方案的安全性及经济性进行初步评估。并针对抗浮锚杆的设计提出了具体建议。

Abstract:The provisions of calculation of bearing capacity of anti-floating anchor of several codes were summarized, and then through the project example, the joint working model based on Winkler foundation-anchor-baseplate principle was established. The influence of anchor arrangement, anchor stiffness and baseplate thickness in anchor and baseplate force were analyzed and summarized. The tension uneven distribution coefficient of anti-floating anchor was put forward to make a preliminary assessment of the safety and economy of the anti-floating anchor arrangement in the basement. Some suggestions were put forward for the design of anti-floating anchor.

Keywords:anti-floating anchor; layout of anchor; stiffness of anchor; uneven distribution coefficient
