Study and Practice of Controlling Anchorage Force Loss of Prestressed Anchor Rope

The anchorage force loss of the prestressed anchor rope results in reduction or loss of anchorage force, which poses an enormous threat to the project safety. In the conceptual design process, factors like the system , structure, spacing and tonnage of anchorage, and properties of rock and soil should be considered and measures should be taken to effectively control or reduce the effect of the anchorage force loss, which possesses great theoretical and practical significance on the design, construction , safety and social-economic benefits of the anchorage project. Finally, the validity and reliability of design measure was proved by an engineering example.
