| 摘 要： | 本文对大跨度的斜张桥进行空间分析，推导出在用空间分析时的一般情况下索面单元的刚度矩阵和平行索情况下的刚度矩阵，用推导出的结果分析了一个工程算例，计算结果表明对于大跨度的斜张桥采用空间分析是必要的。

| Abstract: | This paper provides the space analysis for large span cable stayed bidges, drives the rigidity matrices of cable element under both general conditions and parallel cable conditions in the space analysis, analyse an engineering illustrative example by using the derived results. The result shows that the space analysis is necessary in analyzing large span cable stayed bridges. |
