| 摘 要： | 目前斜拉-自锚式悬索连续协作体系桥梁在实际工程中应用很少,大多数停留在方案设计阶段。针对汉中市西二环大桥,提出了三塔斜拉-自锚式悬索连续协作体系桥方案。该桥型不仅兼备了斜拉桥和自锚式悬索桥的优点,又有其自身结构新颖、经济美观的特点。文章对该桥进行了方案比选设计,对推荐采用的三塔斜拉-自锚式悬索连续协作体系桥提出了初步的施工方法。

| Abstract: | currently, the cable stayed-self anchored bridge with continuous suspension system is seldom applied in practice. Most of them are at the stage of the scheme design. Based on the bridge on 2nd Ring Road West, Hanzhong City, scheme for cable stayed-self anchored bridge with three towers and continuous suspension system is designed. This type of the bridge is with advantages of the cablestayed bridges and the suspension bridges as well as features novel structure, cost-saving and beautiful appearance. In this paper, schemes for this bridge are compared and designed. Accordingly, the primary construction methods for the recommended cable stayed-self anchored bridge with three towers and continuous suspension system are provided. |
