Monitoring Analysis on Prestress State of Anchor Cable of High Slope of TGP Permanent Shiplocks
三峡永久船闸高边坡锚索预应力状态监测分析

and 3 873 bundles of prestressed anchor cables with grade of 1000 kN and 3000 kN respectively, have been employed to stabilize the high slope of the TGP permanent shiplocks and 113 sets of stress monitors have also been installed to monitor the stress state of these anchor cables. It is rare to have so many anchor cables and stress monitors for a slope in the world. Based on the interpretation and analysis of stress monitor data, the stress state of anchor cables, stabilization effect and loss of prestress are discussed, which will facilitate the safety judgment of high slope stabilization and provide practical experience for other similar projects.
