| Abstract: | The method of interface stress element is very effective in investigating the discontinuous problem of rock mass.By constructing the interface element analytical model for anchored rock,the paper analyses the failure process and the stress distribution around bolt and of bolt-grouting body.The differences are researched on the shear stress distribution around bolt under different bolt diameters,the mechanism of fully grouted bolt is obtained. |
