    • Abstract
  • In order to analysis the influence of roadway cross-section structure on surrounding rock deformation,ANSYS is used for numerical simulation.After comparing the deflections of the surrounding rock under different section shape and different span,the result shows that the section form has an appreciable impact on both the horizontal displacement and the vertical displacement of surrounding rock under the same condition,and the rectangular section has the greatest impact.Both horizontal displacement and vertical displacement of surrounding rock of semicircle arch section all increased with the increasing of roadway span.
