| Abstract: | Geotechnical prestressing cables have been widely used in reinforcement of high slopes.But as a kind of high stress structure buried under the ground in which there are some water contained corrosion mediums together with the fluctuation change of tensioning force,its free section and interior bond section exist long term durability problem.Based on a large amount of monitored data obtained from an actual high slope and laboratory test results,some factors that can influence the long term durability of geot... |
