摘　　要：鉴于格构式输电塔结构具有杆件众多、型式复杂等显著特点,所以建设和发展既安全可靠,又经济合理的此类结构一直是工程界的研究热点和难点。因此,该文提出了一套完整的基于蚁群优化算法的输电塔结构离散变量优化设计方法。该方法是在结构的截面、拓扑和形状变量统一转化为离散变量的基础上,将4类不同层次的优化问题统一为不同规模的标准化旅行商问题,并最终采用蚁群算法实现输电塔结构的优化设计。通过对某一实际输电塔结构的优化设计表明:该文方法不仅可以简单高效的求解输电塔结构的截面、拓扑、形状和布局优化问题,而且清晰明确的阐述了不同优化内容的物理意义和优化准则,实现了优化方法和思路的统一。此外,基于蚁群算法的输电塔结构离散变量优化方法通用性强、易于程序化,而且具有非常好的工程应用前景。Considering the lattice transmission tower structure with varied components and a complicated form, it has been a research hotspot and difficulty for engineers to build and to develop a safe, reliable, economic and reasonable system. Therefore, the structural discrete variable optimization design method based on ACO for a transmission tower is proposed. Based on unifying the cross-section, topology, and shape variables into discrete variables, the optimal problems of four different levels have been transformed into the standardization traveling salesman problems, only with different size. It can be seen from the structural instance of a transmission tower that： the proposed optimal algorithms have a good performance in dealing with cross-section, topology, shape, and layout optimal problems, and clearly illustrate the physical implication and optimization criteria of different optimization components. In addition, the discrete variable optimal design method based on ant colony optimization for a transmission tower structure has some advantages with strong generality and easy programming in computers, and it also has a good prospect in civil engineering applications.
