王家林(北京中弘控股股份有限公司，北京100024)[摘要] 當地下水位較高時，一般采用抗浮錨桿的方式解決抗浮問題。抗浮錨桿施工方便，節(jié)省造價，同時因為抗浮錨桿直徑一般150mm左右，對基礎豎向抗壓承載力影響較小，因此被廣泛用于地下室工程抗浮設計方案中。本文分析抗浮錨桿的布置方式，分析總結了對防水板設計的影響，并對工程應用提出了具體的建議。[關鍵詞] 抗浮錨桿；防水板；彈簧剛度系數；非線性；基床系數中圖分類號：TU46 文獻標識碼：A 文章編號：1002-848X(2012) S2-0517-03Layout of anti-floating anchor and the design of waterproof boardWang Jialin( ZhongHong Holdings Co., Ltd., Beijing 100024, China)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
