| 英文摘要 | The instability of engineering rock mass is usually associated with the failure of discontinuous joints. Pre -tensioned bolts can significantly improve the stress state of fractured rock mass and enhance its strength to resist tensile and shear deformation. To investigate the action mechanism of the bolt applied in the fractured rock mass, this paper developed an analytical approach to describe the performance of a pre-tensioned bolt pene-trating rock joint. The stress state and deformation characteristics of the pre-tensioned bolt are analyzed considering the interaction between the bolt and rock block. Then, numerical validation is carried out and a model of fractured rock mass is established using the Continuum Discontinuum Element Method (CDEM). Uniaxial compression tests of the model under different bolting parameters are carried out. The influences of bolt spacing and pre-tensioned force are analyzed and the apparent mechanical parameters of reinforced rock mass are obtained. |
