摘　　要：根据箱梁预制工艺的要求,模具的周转周期T2通常为3～5 d,而文献[1]中制梁台座规模优化算法仅适合于模具的周转周期T2=1 d的情况。针对文献[1]的局限性,试图通过作图、试算和归纳等一系列工作,找出适用于T2=[1,T1]时计算最优制梁台座数和模具数的通用算法,进一步扩大了算法的适用性。同时,结合文献[1]的工程实例,利用Matlab语言编程验证了改进算法的可行性。According to the requirements of box girder prefabrication process, the turnover cycle of mold is usually 3 -5 days, but the optimization algorithm for the scale of girder-fabrication bed in the literature 1 is only suitable for those modes with turnover cycle of l day. So, contrary to the limitations of the literature, after a series of work including mapping, calculating, generalizing, this paper proposes universal algorithm for computing the optimal number of the girder-fabrication bed and its mold when the turnover cycle is the any integer at the interval 1 and T1, so as to further expand the applicability of the algorithm. Simultaneously, in combination with those project examples in literature, the feasibility of this improved algorithm is verified by Matlab programming.
