摘　　要：圆柱形塔柱是索道常用的支架形式,在承受较大荷载时需对其进行加固。采用ALGOR有限元分析软件建立了4种加固支架塔柱的模型,计算出各种模型在最不利荷载组合下的位移,并对计算结果进行了比较分析。结果表明:经过加固的支架塔柱变形会大大减小,不同加固方式的效果有所不同,当支撑设置在地面或相邻支架根部时加固效果最好。Cylindrical tower column are commonly used as cableway bracket,which need to be reinforced when subjected to large load. This paper established several strengthened tower column models by Algor finite element analysis software,the displacement of the various models under the load were calculated. The results showed that the deformation of the strengthened tower column decreased greatly,and the effects of strengthening modes were different from each other,the effect was the best when the tower roots were set in the ground or the bottom of adjacent bracket.
