| Abstract: | Based on laboratory tests and theoretical analysis, the enhancing function of bolting support to the peak and residual strength and improvement to the E, c and values before and after peak strength of bolted rocks surrounding roadways are studied. The extent is also discussed to control the plastic and broken zones of surrounding rocks under the bolted action. |
