Anchorage Effect on Rock Mass by Discontinuous Deformation Analysis for Rock Failure Method

摘要

In this paper, some numerical simulations for anchored-fractured rock masses are conducted on the basis of the modified discontinuous deformation analysis for rock failure (DDARF) method and the process of damage of the surrounding rocks of the cavern are simulated. Then, the supporting methods of the surrounding rocks of the roadway are optimized. At the last, the effect of anchor on fractured rock mass are studied through monitoring the displacements of the key points and some conclusions are given for engineering application.
