| Abstract: | This paper applied the finite element software of 2D—σ to make a numerical analysis of deep parallel roadways stability in structural stress field .It emphasisly discussed the character of deformation,the development character of yield region ,the stress distribution character and the dynamic evolution procession of deep parallel roadways sourrouding rockmass.The paper demonstrated the failure mechanism of surrounding rockmass and the dynamic relation between the structural stress and deformation and failure .It also presented the rational spacing of rock pillar. |
