| Abstract: | The deteriorations of tensioning plates atop V-shape piers of a prestressed concrete continuous box girder bridge are severe.In this paper,the finite element method is used to carry out simulation calculations of the plates and V-shape piers.The causes leading to the deteriorations are analyzed and measures for strengthening the plates and piers are proposed. |

| Keywords: | prestressed concrete structure V-shape pier simulation analysis bridge strengthening |
