宁波南翔桥V墩实体分析

Analysis of the V-pier of the Nanxiang Bridge in Ningbo with solid element model

V墩连续刚构桥由于造型美观,经济性较好,近年来有不少应用。V墩连续刚构的斜撑与梁和基础刚接,其交叉处受力比较复杂,必须细致地研究处理,避免出现裂缝。通过对宁波南翔桥V墩的实体分析,优化了空心与实心截面的过渡倒角,加大了0号段底板的圆弧半径,合理配置了普通钢筋。宁波南翔桥V墩设计及分析结果可为类似结构提供一定的参考。

Because the continuous rigid frame box with V-pier is aesthetically pleasing and economic,there are a lot of applications in recent years.The V-pier is a rigid connection between the girder and foundation,the complex stress at the intersection must be carefully studied to avoid cracks.According to the solid finite element analysis of the V-pier of the Nanxiang Bridge,the transition chamfer of solid and hollow section was optimezed;the radius of the circular arc of section 0 was increased with reasonable reinforcement.The design and the solid analysis of the Nanxiang Bridge in Ningbo can provide some reference for the similar structure.
