Abstract
The bolt anchorage with tension force and shear force are studied numerically by FLAC3D modelling. A tri-linear material model was utilized for the bolt steels in order to simulate the strain hardening behaviour of the materials. The numerical modelling show that different types of bolts have similar load capacities, while their deformation capacities are different. The numerical results match the laboratory test results. The different deformation capacities of rock bolts are attributed to their different bonding conditions and stretching lengths. The axial load in the rebar bolt reduces exponentially from the loading point close to the joint to the bolt end. The axial load in the D-Bolt has its maximum at the joint and reduces slowly as the distance from the joint increases.
