预应力锚杆设计分析

The Analysis and Design of Prestressing Anchors

为防止地下水作用导致整体上浮和局部壁板应力过大,加之潮湿环境下抗裂耐久性要求,埋入土体中的空腔地坑槽、高层建筑地下室和钢制槽罐应优先采用预应力锚杆进行处理。文章就其工作机理、制作施工、设计计算及优化做了粗浅探讨,以便与同行业者共勉。

In order to prevent groundwater from floating on the whole and excessive stress on the local wall,besides to meet the requirement of crack resistance and durability in humid environment,we should first take the use of prestressing anchors for treatment to the cavity trenches buried in soil and basements of high-rise buildings and steel tanks.On this paper,we take a simple discussion of it’s working mechanism,fabrication,construction,design calculation and optimization,with the aim of encouragement with colleagues in the same industry.
