摘要: 考虑斜拉索直径、塔架高度和斜拉索与塔架连接间距三方面因素,利用有限元法对斜拉跨越的结构 形式进行优化分析。结果表明,斜拉索的尺寸变化对结构的强度影响不大,而对结构的变形影响很大,其中斜拉索的直径以从管架桥中间到两边逐渐减小的分布形式最好。塔架高度变化对结构的变形影响不大,而对结构的强度影响很大,塔架高度为46m 时结构的强度更好。斜拉索与塔架的连接间距变化对结构的变形影响很小,而对结构强度影响很大,当间距为7.5暳10-2 m 时结构的强度更好。

Abstract: Considering the diameter of diagonal cable, the height of tower and the connection distant of diagonal and tower, the optimizing analysis was done for the structural form of pipeline crossing diagonal cable type structure by the finiteelement method. The results show that the change in diameter of diagonal cable little influences the strength of structure, but largely influences the deformation of structure. The distribution form of the diameters of diagonal cable which gradually reduce from middle to both ends of the pipe bridge is best. The change in height of tower little influences the deformation of structure, but largely influences the strength of structure. The strength of structure is best when the height of tower was 46 m. The change in connection distant of diagonal and tower little influences the deformation of structure, but largely influences the strength of structure. The strength of structure is best when the connection distant was 7.5×10-2 m.
