摘要
中山市歧江大桥为三跨双塔单面索预应力部分斜拉桥,主塔鞍座采用新型索鞍结构.介绍该主塔鞍座节段模型试验,研究鞍座处索鞍下部混凝土的受力性能及应力分布情况,对主塔节段进行有限元空间分析,判定新型索鞍结构的合理性.
A new pattern cable saddle structure is used in main tower of Zhongshan City Qijiang River Bridge. Main tower segment model test and behavior of concrete are introduced in this paper. Finite element spatial model is established to analyse the model structure. The results show the stress distribution of the tower saddles and draw a conclusion whether the new pattern saddles structure is reasonable or not.
