| 摘 要： | 斜拉桥混凝土主梁庞大的重量都是通过斜拉索与钢锚箱将力传递到索塔上，作为传力载体和对斜拉索线型起控制作用的钢锚箱的定位精度成为直接影响斜拉桥的内力分布、成桥线型的重要因素。如何有效地考虑这些不利的影响因素成为保证斜拉桥梁上钢锚箱定位精度的关键所在。

| Abstract: | The weight of the girder cable-stayed bridge concrete is transmitted to cable tower through huge stay cables and steel anchor box. As the main carrier of force transmission and controlling the line type of stay cables,the positioning precision of steel anchor box of cable-stayed bridge will be the key factors directly affecting the internal force distribution and the bridge line type. How to effectively consider these disadvantageous influencing factors are the key to guarantee the position precision of steel anchor box. |
