Study on Stress Characteristics of the Anchor Bolts in Special-Shaped Roadway

Abstract:

Rock bolting is one of the most common methods of rock reinforcement. To optimize bolt parameters for reasonably playing its properties under safe support condition, it’s a must to study the mechanical characteristics of roadway and bolt. This paper shows that anchor bolts at the top of the rise side has the maximum force, middle of the two sides minimal. Middle of two sides has the largest displacement, top and bottom smallest by using flac3d to simulate the force of special-shaped roadway under the support of anchor bolts, combined with field observance of anchor bolts force. Therefore, by optimizing anchor bolts supporting parameters, we can effectively control the deformation of surrounding rocks and improve the whole stability through strengthening support and changing partial anchor bolts supporting parameters.
