摘要
以江肇高速公路西江特大桥为背景,研究宽幅脊骨梁矮塔斜拉桥截面正应力分布规律。通过理论计算并结合实桥试验验证,得出了各关键断面应力不均匀系数,为优化预应力钢束设计及改善宽幅截面受力性能提供了依据。
Taking Xijiang Bridge in Jiangmen – Zhaoqing Expressway as the background, the article studies the normal stress distribution rule at the section of wide-backbone girder low-pylon cable-stayed bridge.According to the theoretical calculation and the experimental verification of real bridge, the uneven coefficient of each key section stress is achieved so as to provide the basis for optimizing the design of pre-stressed steel beam and for improving the stress performance of wide section.
