摘要:

 利用mindlin解推导所得锚杆加固岩体的锚杆轴力分布以及锚固界面剪应力分布规律,研究了影响锚固岩体应力分布的参数。进一步讨论锚杆加固岩体材料的耐久性与其应力分布规律之间的关系,并得出重要结论,为锚杆加固定量设计及相关工程实际应用提供了理论依据。

关键词:  , 锚杆 岩体 应力 耐久性

Abstract:

The distribution laws of the axial force in the bolt and the shear force on the interface of boltrock, which is obtained through mindlin solution, are presented in this paper. And the parameters which influence the force distribution are also analyzed. After that, the relationship between the durability of boltrock combination material and its stress distribution are discussed, and some important conclusions are drawn, which can provide the theoretical support for the design and application of bolt reinforcement.

Key words: bolt  , rock  , stress durability
