摘要

摘要: 在论述了扩体锚固技术发展历程以及扩体锚杆的承载特性和破坏模式的基础上,阐述了与传统等直径锚杆相比,扩体锚杆的承载特性的优越性和破坏机制的合理性。基于扩体锚杆的众多优势,研发了具有多重防腐功能的承压型囊式扩体锚杆,并详细介绍了该种锚杆的结构型式、施工技术、施工设备和地基土性适用条件。最后结合一些典型的承压型囊式扩体锚杆应用案例,论述了该种锚杆目前在中国的推广应用现状。

Abstract: Based on the description of the developing history, the bearing capacity and failure mode of under-reamed ground anchor, the advantages of its bearing capacity and the rationalities of its failure mode are elaborated compared with those of normal tension-type anchor. According to the advantages of under-reamed anchor, a capsule-type under-reamed anchor with multiple anti-corrosion function is developed. Besides, structure, its construction technology, construction equipment and the applicable soil conditions are all discussed. Finally, combined with some classic applications of the capsule-type under-reamed anchor with multiple anti-corrosion function, the current situation of its promotion and application in China is introduced.
