摘　　要：以2008年受冰灾较为严重的湖南省郴州市为例,基于实地调查所取得的大量资料,剖析了2008年1月以来由于冰覆引起的大量输电塔倒塌的主要原因.研究表明:严重覆冰所引起的输电塔超载、输电塔布局不合理所引起的不平衡力等是造成冰雪灾害中大量输电塔倒塌的主因;同时提出了输电塔设计改进的建议,为最大限度减少类似灾害造成输电塔损失提供参考.Taking the collapse of Power Transmission Tower in Chenzhou city,Hunan as the study case,the causes of the tumbling incident are thoroughly analyzed based on a wealth of first-hand information,including the pressure resulted from excessive amount of ice mass on the top of the power transmission towers,the unbalanced forces on the irrational locations of the tower,etc.In the end,the amendments for the design of power transmission tower are proposed,and some measures are suggested aiming at minimizing the loss of power transmission towers for the next possible snowstorm.
