摘　　要：本文结合一个4m 3分格的塔腿辅材拓扑优化实例,较为详细地说明了利用相对差商算法进行输电塔塔腿辅材拓扑优化的思想与策略。从算例可以看到,利用这种方法节省了约35%的材料,且仅仅用了11步就完成了整个优化过程,这足以说明该种优化算法是高效可行的。在本文的最后作出了对输电塔塔腿辅材的拓扑优化的几点总结。By the sample of a real transmission tower, which＇s leg is 4 meters high and divided into 3 sections, the optimization method of relative difference quotient algorithm is described in detail, and a strategy is proposed to optimize the redundant member of transmission tower＇s legs by this method. About 35% matierials are decreased during the processing of optimization, which is completed in only 11 steps. And some cruxes for optimizing the redundant member of transmission tower＇s legs are summarized at the end of the thesis.
