摘要
文章以永鑫大桥为研究对象,采用子模型计算方法对永鑫大桥墩梁塔固结部位进行有限元计算,分析了该部位的局部应力及横、竖向预应力设置对该区域的影响,其计算结果可为同类矮塔斜拉桥设计提供参考。
With Yongxin Bridge as the research object,the article used the submodel calcula- tion method to conduct the finite element analysis for tower-beam-pier consolidation part of Yongxin Bridge,analyzed the local stress of this part as well as the impact of horizontal and vertical prestressing setting on this region, and its calculation results can provide the refer- ence for the design of similar lower tower cable-stayed bridges.
