| Abstract: | Highway bridges, after a period of in-service, would experience beam cracks and other diseases due to torsion.The concrete external pre-stress, widely used in the old bridge strengthening, can effectively improve the bearingcapacity of the bridge. This paper, based on some construction practice, analyzes the anchorage, pre-stressed tension,pipes and grouting points, aiming to provide reference to other similar projects. |

| Keywords: | external pre-stress concrete tension |
