摘要
抵抗结构的上拔荷载目前已成为工程建设中一个经常面临的问题。采取压重式的抗拔措施增加了土方量或砼量 ,因不经济而较少采用。经常采用的措施是使用抗拔桩或抗拔锚杆。由于目前对抗拔桩锚的抗拔承载机理缺乏深入了解 ,设计计算理论尚不成熟 ,并且没有现成的规范作为设计依据 ,因而在一定程度上影响了抗拔桩锚技术的推广应用。本文对不同类型的抗拔桩和抗拔锚杆分析作了介绍。
The problem how to resist the pulling force on the structure is often met in today's engineering construction. It is not economical to solve the problem by adding soil and concrete to increase the pressure. Usually, the pulling resistant pile and anchor was used. To a certain extent, the expanding and applying of this method nowadays is limited because there is lack of knowledge about the mechanism of the pulling resistant pile and anchor, the incompleteness of the design theory and it is not included in any existed specifications. In this paper different kinds of pulling resistant pile and anchor are introduced to provide a reference for the professionals.
