摘要
某预应力混凝土连续箱梁桥的V形墩墩顶拉板病害严重,采用有限元法对V形墩进行仿真计算。分析了V形墩病害产生的原因,并提出了加固措施。
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.
