Research on Influence Factors of the Distribution Form of Concentration of Prestressed Soil Anchor Side Friction
Translated Abstract
Prestressed anchor has been widely used in underground engineering, such as foundation excavation, tunnel and so on. Concentrated tension prestressed anchor with its unique advantages favored. However, for the lagging understanding of the anchoring mechanism and the bearing mechanism, it needs to be improved. In this paper, through analysis of the soil and construction parameters, to research on the problems such as the bearing capacity of anchor, prestress loss. And the results show that with the increase of bolt free length, the anchoring section of average frictional resistance improved significantly. The bearing capacity of the anchor rod increased with the increase of anchorage length, but the anchoring section of average frictional resistance is decreasing, which suggests that the utilization rate of the anchoring declines.
