深基坑支护新技术锚管桩的设计

Bolting pile design a new technology for deep foundation pit support

深入介绍了一种深基坑支护新技术———锚管桩 (也称锚杆 )的形成、作用及应用范围 ,详细计算了锚管桩抗拉承载力及其设计值以及土体整体稳定性的验算。并说明了未考虑的计算内容及施工图设计的注意事项与设计参数的修改、调整。

A new technology for deep foundation pit support bolting pile is simply introduced. The formation, function an application scope of this kind of pile are elaborated, and the tension bearing capacity, its design value and checking calculation of integral stability are calculated in detail. At last for some unconsidered calculation content, matters needing attention in construction documents design and the modification and adjustment of design parameters this paper give detail illustration.
