| 摘 要： | 输电铁塔结构在设计中存在许多不确定性因素,对其进行可靠度分析非常重要。利用概率论知识估算500 kV输电铁塔实际可靠度的方法,建立了500 kV输电铁塔可靠度简化计算模型,并根据工程实际确定了失效模式个数。最后通过算例利用窄界限法计算了其可靠度。

| Abstract: | There exist many indeterminable factors in design for the transmission line tower structure,so it's ver- y important to analyze its reliability.By using the method that 500 kV transmission line tower actual reliability was estimated through using probability knowledge,500 KV transmission line tower simplification model was es- tablished,and its failure model numbers was computed according to real project.Finally,its degree of reliability was computed by Ditlevsen method through an example. |
