| Abstract: | With the application of numerical simulation software FLAC2D,this paper has simulated the deformation and failure regularity of surrounding rocks with bolt support for soft rocks roadway,and also analyzed the surrounding stress,displacement and plastic zone accordingly.After analyzing the results from both numerical simulation and field actual measurement,the author finds that bolt support for soft rock roadway can effectively control the large deformation of surrounding rocks in depth and stabilize the roadway surrounding rocks. |
