摘要: 危岩崩塌是一种全球泛生型重大地质灾害,其应急加固技术是危岩崩塌应急减灾的关键环节。研发了一种新型锚杆(自锚型应急锚杆),详细阐述了自锚型应急锚杆的结构组成和使用 方法;建立了自锚型应急锚杆和锚杆螺栓的抗剪强度计算方法,获得了治理危岩所需锚杆数量的计算式。研究成果为应急治理危岩崩塌灾害提供了一种新技术,并可推广应用于房屋结构及桥 梁结构的应急加固中。

Abstract: Perilous rock and collapse is a kind of major global geological disaster and its emergency reinforcement technology is the critical link of emergency disaster mitigation of perilous rock and collapse. A new type of anchor that is self-anchored emergency anchor was proposed. The structure composition and application method of self-anchored emergency anchor were expounded in detail. The shear strength calculation method of self-anchored emergency anchor and bolt of anchor arm was established, and the calculation formula of the amount of anchor needed to control dangerous rock was obtained. The research results provide a new technical path for emergency treatment of perilous rock and collapse, which can also be applied to the emergency reinforcement of building structure and bridge structure.

Key words: geotechnical engineering, rock mechanics, emergent reinforcement of perilous rock, self-anchored emergency anchor, perilous rock and collapse
