| Abstract: | A lot of prestressed anchorage cables have been embedded in rock mass of high slope during lst stage construction of TGP's permanent lock.The string dynamometers have been installed on parts of anchor bolts.The causes of various problems appeared during installing string dynamometers and monitoring procedure are investigated.The various characters and change tendency of anchorage prestress ,as well as the effects of group anchorages,etc.,are comprehensively analysed.Finally,the construction qualities and anchoring effects are evaluated. |
