| 摘 要： | 从结构构造和力学特点两个方面进行对比分析,得出斜拉桥随着跨径的增加,拉索与主梁的夹角逐渐变小,竖向有效分力也随着变小,因此,斜拉桥的跨越能力会受到限制,推导了最佳的高跨比范围;悬索桥吊杆与加劲梁是垂直或斜向交叉,不会随着跨径加大而受影响,悬索桥比斜拉桥的跨越能力更大.

| Abstract: | This paper analyzes two sorts of bridges from structure features and mechanical characteristics.The angle of cable and main beam of cable-stayed bridge is small when the span of the bridge is very big,and the vertical force is very small.While the angle of suspender and stiff girder of suspension bridge is vertical it won't be influenced by the increase in the span.The capacity of suspension is bigger than that of the cable-stayed bridge. |
