摘要
为了提升锚杆支护下围岩的稳定性,通过MATLAB软件对不同支护参数下围岩加固体的弹性模量、泊松比及黏聚力的变化趋势进行分析,并对不同弹性模量、泊松比及锚杆长度下围岩稳定性系数进行分析,给出了参数的变化趋势,为巷道围岩锚杆支护提供一定的参考与借鉴。
In order to improve the stability of surrounding rock under bolt support,the change trend of elastic modulus,Poisson's ratio and cohesion of surrounding rock reinforcement under different supporting parameters is analyzed by MATLAB software,and the stability coefficient of surrounding rock under different elastic modulus,Poisson's ratio and bolt length is analyzed.The change trend of parameters is given,which provides some reference and reference for roadway surrounding rock bolt support.
