| Abstract: | The article analyzes the calculation of extension value when the prestressing tendon is tensioned. Based on the construction practice,the article introduces the usage of the measured resuhs of extension value,theoretically analyzes the reason to cause the prestressing stretching extension value slightly large or slightly small,and demonstrates the analyzing reasonableness by the projects. |
