摘要: 锚杆(索)加固方案设计的一个重要方面就是锚杆长度的合理选取,它的选取应该既保证经济,有足够的安全度,又不至于过长,从而增大锚索(杆)的长度,造成不必要的浪费.基于此,本文根据锚杆破坏受力情况分析,提出锚杆锚固段合理设计长度.

关键词: 锚杆, 锚索, 锚固段设计长度

Abstract: How to decide the reasonable bond length of grouted bolts in rock is the primary element in structural reinforcement design.Safety and economy is the basic requirements.The paper presents favor bolt length in rock using models of elasticity properties,brittle cracking of grout and safe consideration and also shows that geometry of borehole and bolt are all relevant parameters in the development of the bolt grout interface pressure which result in bond strength increasing.

Key words: bolt, cable, bond length
