| 摘 要： | 索塔锚固区是斜拉桥的关键部位,将拉索的集中力安全平稳地传递到塔柱中。该区域受力状态复杂,是斜拉桥设计施工中的重点和难点。目前常用的索塔锚固方式有环向预应力、钢锚梁和钢锚箱三大类,对三类锚固方式作了详细的介绍,比较分析了各自的优缺点,为相关工程提供参考。

| Abstract: | The cable pylon anchorage zone is the key place of cable-stayed bridge to safely and smoothly transmit the centralized force of cable into the pylon column.The stress state of this zone is complicated,and is the keynote and difficulty in the design and construction of cable-stayed bridge.At present,there are three kinds of cable pylon anchorage modes,i.e.hoop prestressing,steel anchor beam and steel anchor box commonly used in the construction.The article introduces three kinds of anchorage modes in detail,compares and analyzes the advantages and disadvantages of these modes,which can be referred for the similar projects. |
