摘要: 隧道电缆支架角钢托臂的弯曲特性较为复杂,选型设计不当会给电缆线路运行带来严重安全隐患。以某地区110 kV电缆隧道工程为背景,利用有限元软件ABAQUS建立电缆角钢支架的三维精细化模型,对悬臂角钢构件在集中荷载作用下的破坏模式和荷载-位移曲线进行研究,同时完成系列参数影响分析,给出设计建议。

Abstract: The bending characteristics of angle steel bracket arms for tunnel cable supports exhibit considerable complexity, and improper design and selection can pose serious safety risks to the operation of cable lines. Take a 110 kV cable tunnel project in Jining area as a background, a three-dimensional refined model of the cable angle steel bracket is established using the finite element software ABAQUS, which is utilized to investigate the failure modes and load-displacement curves of cantilever angle steel components subjected to concentrated load. Meanwhile, a series of parameter influence analyses are completed, and design recommendations are provided.

Key words: cable supports, cantilever angle steel components, flexural stability bearing capacity
