What is the role of anchors bar/rock bolt in tunnels?
The role of tunnel anchors is mainly to reinforce the geotechnical body, control deformation and prevent collap
Anchor bar through the weak, loose, unstable rock and soil body, anchored in the deep end of the stable rock and soil body, to provide enough tension to overcome the self-weight of the sliding rock and soil body and the downward force, to prevent the wall of the cave from sliding and collapsing.
After the anchor bar is stressed, a compression zone is formed in a certain range around. The anchor piece will be arranged in an appropriate way, so that the compression zone formed by neighboring anchors overlap each other to form a compression zone. The loose stratum in the compression zone is reinforced by the anchors, the integrity is enhanced and the bearing capacity is increased.
Anchor bar inserted into the stratum at a certain depth, in the anchoring force under the action of the stratum of mutual compression, interlayer resistance increases, internal stress and deflection greatly reduced, equivalent to the simple superposition of several layers of beams (arches) into a combination of beams (arches). The flexural rigidity and strength of the combined beam (arch) are greatly improved, thus enhancing the bearing capacity of the ground. The larger the anchoring force provided by the anchors, the more obvious the role
