| Abstract: | Relying on Changqingsha II Bridge（cable-stayed bridge）engineering project in Rugao City,Jiangsu Province,through the prestressed tension test,the article measured the actual friction loss of U-shaped prestress tendons, used the least square fitting to obtain the pore friction coefficient and the variation coefficient,and verified the rationality of such prestressed structures. |
