摘　　要：提出了一种基于上限准则的根开优化方法,首先确定了两种形式节间的重量随着根开增大呈台阶式下降的趋势,然后证明了输电塔根开上限的存在,进一步提出了根开最优化准则及其计算流程,最后,对一座真实的输电塔模型采用此方法进行了优化计算,结果表明,使用该方法可以达到优化的目的,并具有计算过程稳定以及全局最优性的特点。Root span is the most important shape of a transmission tower. In this paper, an optimization method for transmission tower＇s root span by upper limit criterion is proposed. Step type downward trend is found when the weights of two different representative panels variety. And the upper limit of root span is proved to exist due to aesthetics, then an optimal calculation procedure is given. Finally, a real sample is cited by using this method. Rcsult shows that a lighter design can be reached, and it also shows that this method has advantages such as highly-efficient, stable and global optimality etc according to the calculation process.
