摘要
抗拔锚杆的工作原理是利用锚杆与土层之间的摩擦力,对基础底板上浮的趋势进行约束,起到抵抗基础上浮的作用。与其他抗浮措施相比,具有造价低、施工速度快等优点,广泛应用于地下室抗浮设计。论文结合抗拔锚杆在合肥通用机械研究院研发中心工程地下室中的应用,介绍和说明锚杆的施工工艺。
Anti-pulling bolts use the friction force between bolts and soil to restrict the rise of base plate in order to resist base floating.Compared with other anti-floating approaches,anti-pulling bolts are cheap to make and can work very efficiently,therefore they have been widely used in anti-floating design for basements.This essay,based on the utilization of anti-pulling bolts in the basement of Hefei General Machinery Research Center,will introduce and illustrate the construction technology of anti-pulling bolts.
