摘要
钢管杆具有占地面积小、节约线路走廊、结构简单、施工方便的特点,在地形受限制和走廊拥挤的城市地区架空输电线路中得到了广泛的应用。但钢管杆线路综合单位造价较高,为节约投资,钢管杆线路本体的优化设计在工程造价控制中有着至关重要的作用。对钢管杆的荷载及受力特性、设计控制因素进行深入分析,并基于案例探讨了钢管杆的优化设计要点。
Steel pipe poles have the characteristics of small footprint,saving line corridors,simple structure,and convenient construction.They have been widely used in overhead transmission lines in urban areas with limited terrain and congested corridors.However,the comprehensive unit cost of steel pipe pole lines is relatively high.In order to save investment,the optimization design of the steel pipe pole line body plays a crucial role in engineering cost control.An in-depth analysis was conducted on the load and stress characteristics,design control factors,and optimization design points of steel pipe poles were discussed based on case studies.
