斜拉桥混凝土索塔钢锚箱受力计算

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大跨度斜拉桥中应用。介绍两种常用的混凝土索塔钢锚箱锚固区结构形式，以苏通大桥为例对两种结构形式分别建立空间实体模型，进行结构受力分析。

Analysis of Mechanical Behavior on Concrete Pylon Steel-Anchor-Box in Cable-Stayed Bridge

The structural form of concrete pylon steel-anchor-box has been applied in the anchorage zone of a large span cable-stayed bridge, because it has advantages of clear mechanical pattern and convenient con- struction. Two kinds of structural forms that were usually used in engineering were introduced and their spacial models based on Sutong bridge were established respectively. The mechanical results of different models were obtained and useful conclusions were provided after comparing the mechanical results.
