摘　　要：以大型的岩土工程数值分析软件AD INA为研究手段,对边坡岩体的分离块体经系统锚杆加固后,其抗压强度、弹性模量及c、φ值的提高,并计算和比较了锚固对不同强度岩体的参数影响大小,并对锚固岩体的各向异性进行了初步研究,垂直布锚对岩体的弹性模量影响较大,但是对于岩体的抗压强度的影响相对较小。By using the numerical model analysis software ADINA developed for large - scale geotechnical engineering problems, the improvements to the compression strength, elastic modulus c and φ values of the separate rock blocks after systematic bolts reinforcement are discussed , and the influence degree of systematic bolts on the rock mass of different strength is analysed. The anisotropy of the reinforced rock mass is also preliminarily studied, and it is found that bolts of vertical arrangement have major effect on the elastic modulus of the rock mass, but have minor effect on its compression strength.
