摘　　要：以假设杆件全部除去时的支撑点数和支撑反力的累计总和为目标函数 ,利用改进遗传算法求解桁架结构的最优施工路径优化 ,编制相应的程序 ,完成层状桁架结构的施工路径优化问题设计 .算例表明 ,利用改进遗传算法有可能得出更优的解 .Taking cumulative total of supporting points and bearing reaction as objective function in case all members are removed, drawing on the successful experience from solving problem similar to optimizing planning, the authors use the improved genetic algorithm for optimizing construction planning in solving truss structure; and compose corresponding program; and complete optimizing design of construction planning for layered truss structure. Computing examples indicate that it is possible to obtain better solution by using improved genetic algorithm.

关 键 词：桁架结构 施工路径 优化设计 改进遗传算法
