The Sinorock rock bolt was applied widely in the tunnel construction. However, the traditional equilong rock bolt can not connect the surrounding rock effectively in the nearly zone and the shear stress on is so large to lead to the length limitation. While the combination of the long rock bolt and the short rock bolt can foster strengths and circumvent weaknesses. The supporting effect is definitely better.
