摘　　要：通过数值计算,模拟了支护与注浆加固两帮后巷道的顶底板围岩稳定性。模拟结果表明,对巷帮加固处理后围岩顶底板变形量减小,承载能力增强,巷道围岩水平应力增大,顶底板破碎区与塑性区范围缩小。从而得出巷道两帮的加固有利于巷道顶底板围岩的稳定性。Numerical calculation is used to simulate the stability of surrounding rock of floor and roof,after supporting and grouting the two sides. It turns out that oof and floor rock deformation decrease,the carrying capacity enhances,surrounding rock horizontal stress increases,fragmentation and plastic zone areas reduce after reinforcing the sides. As a result,it is conducive to maintain the stability of roof and floor rock with the sides reinforced.
