Moreover, the anti-floating computation will be depended on several conditions not only such as the reasonable arrangement of anchors, tensile stiffness of anchors, base plate stiffness, the vertical load application, but also base plate support conditions, which intends further analysis will be necessarily needed. Hence, combined with an engineering example of old city reconstruction, the anti-floating design in a large basement with applied high strength reinforcement anti-floating anchor is studied in this paper.KeyWords: Anti-Floating Anchors, Deep Foundation Pit, High Strength Reinforcement作者简介：何涛，一级注册结构工程师。
