摘要

On account of analytic method and test method are difficult, we use the finite element method on flexible inner pressure bolt, Obtaining: The adjacent formation elasticity coefficient is bigger this kind of anchor rod the anchor effect to be better; Within a certain range, the anchor rod body rubber material elasticity coefficient is smaller is more advantageous in enhances the anchor rod the anchor effect; Increase the coefficient of friction between the bolt and surrounding rock, Can significantly improve the anchor bolt effect; Anchor maximum impedance friction stress uniformly distributed along the axial direction, This causes the flexible note to press the anchor rod to have the big superiority.
