Stress Distribution Law Analysis of Extensible Bolting of Pre-stressed Anchor

More Information
  • Published Date: January 19, 2016
  • In view of the anchorage problems of prestressed bolt in practical application, based on the theoretical basis of anchoring force elastic solution of grouted bolt, we use numerical software MATLAB to research shear stress and axial force distribution of extensible anchoring bolt. Results show that there is plastic and elastic deformation zone under the effect of prestressed bolt anchor segment. Raising the anchor stiffness of the material or increasing the radius rod body can effectively enlarge its stress distribution and reduce the stress peak value. In addition, we study the anchoring length and anchor destruction form, reveal the fracture mechanism of the bolt support and propose some improving measures for field applications.
