[摘要] 当地下水位较高时，一般采用抗浮锚杆的方式解决抗浮问题。抗浮锚杆施工方便，节省造价，同时因为抗浮锚杆直径一般150mm左右，对基础竖向抗压承载力影响较小，因此被广泛用于地下室工程抗浮设计方案中。本文分析抗浮锚杆的布置方式，分析总结了对防水板设计的影响，并对工程应用提出了具体的建议。

Abstract: The anti-floating anchor is commonly used to solve the problem of the ground water lever is lugher. Construction of anti-floating anchor is convenient, save cost, and anti-floating anchor diameter is generally about 150mm, no adverse effect on basis of vertical compression bearing capacity. Therefore, it been widely used in the anti-floating design of basement. The paper analyzes the layout of anti-floating anchor, analyzes and summarizes the impact of waterproof board, made specific recommendation for engineering application.

Keywords: anti-floating anchor; waterproof board; spring stiffness coefficient; nonlinear; coefficient of subgrade reaction
