| 中文摘要: |
| 近年来世界已建和在建主跨大于800m的斜拉桥数座，混凝土索塔钢锚箱的结构形式由于其受力方式明确、施工方便等优点已开始在此类超大跨度斜拉桥索塔锚固区中应用。本文介绍了用于计算混凝土索塔钢锚箱的三种计算方法，并对其计算结果进行了研究比较，结合具体工程计算分析了不同方法的适用条件和精度。 |
| 英文摘要: |
| Several cable - stayed bridges which main span surpasses 800 m have been built in recent years. Concrete pylon with steel anchor box has been used in long - span cable - stayed bridge because of its clear mechanics behavior and convenient construction. In this paper three different methods are introduced to calculate the stresses of the concrete pylon with steel anchor box and the results are obtained respectively. With a practical example the applicability and the precision of them are discussed. |
