    • Abstract
  • Through stress analysis in construction and service stages and based on the relevant interrelated codes and practical examples, the design principles and methods of pressured grout prestressed anti-floating anchor are studied. The related calculations are summarized: the bearing capacities of anchor, prestressed reinforcement and partial bearing pad in the service stage should be examined, and the bearing capacities in the construction stage are also examined. The cracking control principle and checking method at the top of anchor are put forward so as to provide references for designers. The problems about reinforcement ratio and cracking control, load effect in construction stage and strength of anchor body are discussed to summarize and improve the design of pressured grout prestressed anchor.
