Boussinesq解及Mindlin解在预应力锚固岩体中的应用

Simplified Application of the Boussinesq and Mindlin Solutions to Prestress Anchoring Rockmass

在三维有限元计算证明的基础上,本文将Boussinesq解及Mindlin解进行简化,并应用于含软弱结构面的岩体的预应力加固中,从而提出预应力锚索加固岩体软弱结构面时,锚孔深度、锚孔间距的计算公式,为工程设计提供理论依据。

Based on the calculated results verified by the three-dimensional finite element, the Boussinesq and Mindlin solutions are simplified and applied to rock anchor for choosing the depth and interval of anchor holes.
