Paper Title:
The Theory and Stability Studies on Composite Bolted Rock Mass
  Abstract

Firstly, This paper applied the basic principle of composite material mechanics, saw the rock mass, anchor, mortar as a kind of composite material, established micromechanics equivalent model of bolted rock mass, deduced corresponding parameters formula of bolted rock mass equivalent mechanical model. Secondly, we analyzed engineering example by using the finite element software, conducted a numerical simulation research on composite model and discrete roadway model based on the theoretical derivation. Finally, we verified the feasibility and applicability of the equivalent method by comparative analysis on two sides and roof-floor displacement of roadway and surrounding stress of rock. Thus, this paper established a simplified equivalent calculation method accord with the stability analysis of bolting and shotcreting support and the overall assess of support parameters.
