Studying the Bond Performance of Full-Grouting Rock Bolts Based on the Variable Controlling Method

This paper studied the bond performance of full-grouting rock bolts with a theoretical analysis. The variable controlling method was used to study the effect of parameters on the load-carrying force of bars. The results showed that when the bar diameter grew from 15 mm to 25 mm, the maximum force of...
