| 摘 要： | 对内置式钢锚箱索塔锚固区进行足尺模型试验研究,结果表明结构强度足够,但混凝土外端壁和内侧壁混凝土均出现了裂缝,且外端壁开裂荷载较低.根据试验结果及有限元分析,对索塔锚固区进行抗裂设计,为结构优化提供依据. |
| 关 键 词： | 钢锚箱 模型试验 抗裂设计 索塔锚固区 |

| Abstract: | Full scale model experiments of pylon anchorage zone of built-in steel anchor box were researched,the results shown that the structure strength was enough,but the out end walls and inside sidewalls appeared cracks,and cracking load of the out end walls was low.Based on the result of model testl and FEA,this paper made anticrade design of pylon anchor and provided basis for optimization design. |
| Keywords: | steel anchor box model test anticrack design pylon anchorage zone |
