| Abstract: | IThrough the analysis of the result of the observation for long term in a several project example the paper summarizes some the largest factors influenced on the prestressing of anchor bars in the different engineering geological conditions, including creep of strata, relaxation of steel materials, various impact action etc. And it makes the analysis of the action mechanism of these factors to provide the theory foundation for the prevention and treatment of prestressed loss. |
