摘　　要：采用Abaqus有限元软件模拟了不同锚杆长度、直径、角度和间距等不同锚喷支护参数条件下的支护效果,并采用正交试验设计法得出了支护效果的计算结果,采用直观分析法、极差分析法和层次分析法等深入分析了锚杆长度、直径、角度和间距对支护效果的影响。The support effects of different anchor parameters such as length, diameter, angle and distance of anchor bolts were simulated by Abaqus finite dement software,and the calculating result of the supporting effect was obtained by using the orthogonal test design method.With the method of visual analysis, range analysis and analytic hierarchy process, the influence of the length, diameter, angle and spacing of anchor bolts on the supporting effect was analyzed.

关 键 词：锚喷支护 极差分析法 层次分析法
