摘要
根据某输电塔横担断裂破坏的事故情况,采用一阶弹性计算模型,通过对断裂角钢局部和整体进行分析,找出事故主要原因为施工起吊位置选择不当,改变了输电塔的传力途径和受力模型;提出在输电铁塔施工过程中避免类似事故的针对性建议。
Aiming at breakage of cross arm of transmission tower, the paper finds out that the accident is mainly caused by wrong choice of lifting position by means of calculation model for first-order elasticity and locally and integrally analyzing the broken angle iron; it changes the way of force transmission and stress model and proposes some suggestions preventing such accident during construction of transmission towers.
