| Abstract: | This paper introduces the application of section inlargement method in double-curved arch bridge strenthening. The stress condition before and after strengthening are simulated by program Midas. The results show that the carrying capacity is improved, the traffic capacity and service level are raised by structure assessment and reasonable strengthening for double curved arch bridge. |
