| Abstract: | for the round structure, initial manufacture discrepancy may encounter during the period of manufacture and installation, an initial prestressing force will be produced. For explement, hilo, fracture etc, several usual prestressing force because of manufacture discrepancy, the method of elastic mechanics is adopted, the relevant mechanical model is established, through theoretical derivation, a analysis expression of the prestressing force and allowable explement caused by several initial defects is given, it is a direction for the engineering design. |
