| 摘 要： | 针对大缆为空间索的自锚式悬索桥的线形问题,探讨精确确定各吊点坐标的计算方法。先用分段悬链线法确定各吊点的竖向坐标,然后在横桥向建立各吊点的平衡方程,由此得到各个吊点的横向坐标。并以广州市珠江猎德桥主跨设计方案为例,计算大缆各吊点的空间坐标,得到满意的结果。

| Abstract: | For spatial cable curves of self-anchored suspension bridge,a calculation method of the nodes' position is discussed.Firstly the vertical coordinates are calculated by segmental catenary's method.Then,the balance equations are constructed in horizontal bridge direction.The horizontal coordinates of all nodes are got through solving those equations.In addition,a case study of Liede Bridge in GuangZhou,the 3-D coordinates of the spatial cable of the main span are calculated. |
