摘　　要：在地下室底板抗浮设计中,使用抗浮锚杆是工程实践中常用的一种方式,合理的锚杆布置方式及锚杆抗拔承载力的选择能使设计兼顾安全和经济。本文根据实际项目情况,通过有限元建模的方式,比较不同锚杆布置方式及不同锚杆抗拔承载力的选择对抗浮设计的影响,选出最优方案供工程设计参考。In the anti floating design of basement floor,the use of anti floating bolts is a common way in engineering practice.The reasonable arrangement of bolts and the selection of anti pulling bearing capacity of bolts can make the design take into account both safety and economy.In this paper,according to the actual project conditions,through the way of finite element modeling,the effects of different anchor bolt layout and different anchor bolt uplift bearing capacity on anti floating design are compared,and the optimal scheme is selected for engineering design reference.

关 键 词：抗浮设计 抗浮锚杆 布置方式 承载力设计值
