摘　　要：给水管道造价公式的精确性直接关系到给水工程设计的经济性和科学性.造价公式中含有多个待定参数,用传统的方法难以直接优化求解.因此,用微进化算法对造价公式参数进行直接的优化计算,并将其计算结果与传统方法的计算结果相比较.实例计算结果表明:微进化算法的拟合效果较好,提高了造价公式的精度;微进化算法具有易于实现,计算速度快等特点.Abstract： The accuracy of the water pipe cost formula is directly related to economic design ot me drainage works. However, the cost formula contains several undetermined parameters. These parameters are difficuk to be direcdy solved by traditional methods. Therefore, microevolution algorithm for optimization of parameters in water pipe cost formula is proposed. Compared with traditional methods, the results shows that microevolution algorithm is better and the accuracy of the cost formula was improved. In addition, microevolution algorithm is easy to implement and fast in computing.
