| 摘 要： | 引入安全度概念，推导出铁塔安全度计算公式。结合荷载效应比值、国内外标准的风、冰荷载比值等参数，计算得到各国铁塔的设计安全度。结果表明，对于铁塔的设计，我国标准规定的设计安全度与国外标准基本相当。研究成果可为我国输电线路元件的安全设置水平提供参考依据，并且为元件的强度匹配关系的研究做出了铺垫。 |

| Abstract: | The conception of safety degree is introduced in this paper and the corresponding calculation formula for safety degree is deduced.Based on the load effect ratios and other parameters such as the ratio of wind and ice loads recommended in both Chinese and foreign standards,a calculation is made of the design safety degrees of transmission towers in various countries.The results show that the safety degrees stipulated by Chinese standards are basically equivalent to that by foreign standards,which can be used as a reference for designing the safety level of various components of transmission lines in China and will provide a basis for study of the matching strength of components. |
| Keywords: | transmission line tower safety degree load effect wind load ice load |
