Abstract: Based on the theory of numerical manifold method, a model of support with reinforced bolts (cables) was proposed for anchored rock mass. The model can fully reflect the mechanical mechanism of bolt reinforcement of fractured rock mass and imitate the complex geometric distribution and parameters of all kinds of reinforced bolts (cables). The results of numerical manifold method employed show that the model of numerical computation in this paper can preferably reflect the behavior of reinforcement of fractured rock mass by these bolts (cables) and have a vast prospect of application.
