基于灰色理论的斜拉桥拉索安全性评价

Safety-based cables'. condition evalution of cable stayed bridge with grey theory

引用灰色加权关联分析和灰色变权聚类分析的概念,对斜拉桥某索面索力安全性进行整体评价,并以上海杨浦大桥索力变化为例计算分析。结果表明,这两种方法可较好地应用于斜拉桥索面拉索安全性状况的整体评估,结果可供有关养护部门参考。

Safety-based cables'. condition of cable stayed bridge in a cable plane is evaluated with grey correlation analysis and grey variable weight cluster analysis theory through an example. The example shows that these two methods can be easily used in safety-based cables'. condition evaluation of cable stayed bridge in a cable plane. And the results can be reference to relative management department.
