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。
There exist many indeterminable factors in design for the transmission line tower structure, so it＇s very 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 established, and its failure model numbers was computed according to real project. Finally, its degree of reliability was computed by Diflevsen method through an example.
