摘要
利用数值流形方法理论 ,建立了岩体锚杆 (索 )加固的数值流形方法模型 ,该模型反映了裂隙岩体锚固的力学机理 ,可以仿真各种加固锚杆 (索 )的复杂几何布置及几何参数。数值算例表明 :计算模型能较好地反映锚杆 (索 )加固岩体的变形行为 ,具有广泛的工程实用前景。
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.
