Experiment on Ultimate Shear Strength Parameters of Bolt Anchored Section
The bolt support is one of the effective support means to stable the surrounding rocks in underground projects. To determine the ultimate shear strength parameter between the surrounding rocks and bolting mass interface would have important project value to the bolt support design. In order to easy and accurately determine the shear strength of the bolting layer in the bolt design, based on elastic-plastic theory, a theoretical model under the bolt pulling function was established. The load transmission function during the bolt function process was derived. The theoretical relationship between the limit shear strength parameter of the bolting layer interface and the bolt pulling test curve was obtain. The shear strength parameter between the resin anchoring agent of the bolt support in mine roadway and the coal rock mass was determined. The results show that with the bolt pulling test curves, the cohesive strength of the bolting layer and the shearing rigidity coefficient of the bolting layer interface could be easily obtained and could provide the references to the bolt support design.
