索梁锚固结构是斜拉桥的关键部位之一。珠江黄埔大桥采用了锚箱式的索梁锚固结构。根据珠江黄埔大桥索梁锚固结构的静载试验,得到了各板件的应力分布情况,认为板件间连接可靠,锚固结构的承载能力可满足设计要求。通过计算结果与实测结果的比较分析,证明三维有限元方法可以用于估算索梁锚固区的应力分布。
Cable girder anchoring structure is one of the key parts of cable-stayed bridge. Zhujiang Huangpu Bridge anchorage box girder anchorage structure. According to the static load test of the cable-beam anchorage structure of Zhujiang Huangpu Bridge, the stress distribution of each plate is obtained. It is considered that the connection between the plates is reliable and the carrying capacity of the anchoring structure can meet the design requirements. By comparing the calculated results with the measured ones, it is proved that the three-dimensional finite element method can be used to estimate the stress distribution in the cable-anchorage zone.
