Experimental Study of the Failure Mechanism of the Anchorage Interface under Different Surrounding Rock Strengths and Ambient Temperatures

Abstract: In order to study the anchoring instability mechanism of surrounding rock in deep roadway, the failure mechanism of the bolt-anchoring agent interface was studied by simulating different strength rock mass and ground temperature environment, using C20, C40, and C60 strength concrete and steel pipe to simulate different surrounding rock strength environments. Indoor pull-out tests were carried out to study the pull-out load displacement relationship, ultimate pull-out force, residual anchoring force, the distri… Show more

“…The ejection phenomenon of broken anchor cables is common [4,5]. In addition to the influence of load and sudden external factors, the anchoring structure of anchor cables is also subject to damage accumulation, which results in bond failure, pull or shear failure of anchor parts, and other forms of anchorage system failure [6][7][8][9]. Traditional anchor cable design methods have limitations in deep roadway support [10,11].…”
