| Abstract: | By means of numerical simulation software ANSYS,the deformation regularity of bolting support and concrete lining support for deep roadways is numerically simulated.The displacement and the changes in plastic zone of different supports for surrounding rocks are systematically analyzed.The research results indicate that the strength and bearing capacity of surrounding rocks for concrete lining support roadways is greatly increased.So the deformation of deep roadway is effectively controlled. |
