Abstract: The anchoring length and the pre-tightening force are the two main factors influencing the control effect of surrounding rock in bolt support. To study the influences, a theoretical analysis is made on the stress distribution… read more here.

Abstract: Abstract In the bolt tightening control, when the input torque is given, the complicated friction phenomenon at the bolted joint interface will lead to the non-uniqueness of the pre-tightening force. Moreover, due to the coupling… read more here.
