| Abstract: | By the simulation test, it is proved that the function of rock bolt is to raise the residual strength of broken surrounding rock around roadway, and the broken surrounding rock is made into a reinforced arch. The bearing capability of reinforced broken rock arch is also discussed. The result has been applied in engineering, a soft rock roadway, and its surrounding rock got effectively controlled. |
