| 英文摘要 | Currently the design of tension-type anchor cable based on the assumption that anchoring force uniformly distributed in the anchorage segment, but field test show it unevenly in fact. This study established an elastic mechanical model for the tension-type anchor in rock mass and gained anchoring force distribution expression. The exponential expression shows that anchoring force concentrates in part length of the anchorage segment, and the maximum of it is proportional to the freedom segment length and pre-stressing force, inversely proportional to surrounding rock's stiffness and anchor hole's radius. Then, according to the anchoring force distribution law, the anchorage segment was divided into effective anchorage segment and synergistic anchorage segment two parts. A calculation formula for the effective anchorage length was proposed correspondingly. It was found that this length mainly determined by the rigidity of surrounding rock and buried depth of anchorage segment. Designed grout length must be longer than it. Finally, by referenced to a number of engineering examples, a rational range of grout length for tension-type anchor cable was suggested in soft rock and hard rock respectively. |
