| 摘 要： | 荷载是输电线路铁塔设计的基础,水平风荷载又是输电线路荷载的重要组成部分。DL/T 5551-2018《架空输电线路荷载规范》(以下简称《荷载规范》)对GB 50545-2010《110 kV~750 kV架空输电线路设计规范》(以下简称《设计规范》)中导地线水平风荷载标准值计算公式进行了调整。对两规范中的计算公式进行了比较,对两规范的风载荷进行了计算。通过分析和计算结果发现《荷载规范》对输电线路铁塔风载荷的影响规律,为输电线路设计人员选用杆塔提供参考。

| Abstract: | Load is the foundation of transmission line tower design,and horizontal wind load is an important part of transmission line load.DL/T 5551-2018 Load code for overhead transmission lines(hereinafter referred to as Load code)has adjusted the calculation formula of the standard value of horizontal wind load on conductors in GB 50545-2010110 kV?750 kV overhead transmission lines(hereinafter referred to as Design code).The calculation formulas in the two specifications are compared and the wind loads in the two specifications are calculated.According to the analysis and calculation results,the influence rule of Load code on wind load of transmission line tower is found,which provides reference for transmission line designers to select tower. |
