摘　　要：用荷载增量法结合有限元分析技术,通过枚举列出输电塔体系的主要失效路径,提出了蒙特卡洛概率方法,并通过Matlab软件计算出各输电塔体系的失效概率,最后以一大型输电塔进行了可靠度计算。The author uses the load increment method combining with finite element analysis, based on enumerating main failure path of transmission tower structural system, provides Monte-Carlo probability method, and calculates failure probabilities of all transmission tower system based on the Matlab software, finally gets reliability calculation on one large transmission tower.

关 键 词：输电塔结构 可靠度 失效模式 失效概率
