| Abstract: | In terms of point_and_fully_anchoring of bolts, the compression and consolidation effect of anchoring is compared and analyzed by means of Mohr′s circle and shear strengh envelope curve from the shearing parameters of rock mass and the interacting force offered. A new concept about strength reserve is also put forward. In addition, the formula of strength reserve of point_and_fully_anchoring, together with that of the ratio of strength reserve of fully_anchoring to point_anchoring is obtained. |
