摘要
考虑到雨水管网的布置和计算特点,采用枚举算法进行雨水管网的优化设计。针对雨水管网内所有的干管和支管,该算法能够遍历雨水管道可选的标准管径集,找出符合约束条件的所有管径组合,然后利用造价函数筛选出管网造价最低的一种组合,并将其作为最终优化结果。利用Visual Basic 6.0语言编程并进行了工程应用,结果表明,枚举算法可以适用于复杂地形的雨水管网优化,是非常实用的全局优化方法。
Based on the arrangement and calculation characteristics of stormwater drainage system, an optimized design of stormwater drainage system was conducted using enumeration algorithm. By enumerating the normal diameters for each stormwater pipe, the algorithm can find the diameter combinations of manifolds and branches under constraint conditions simultaneously. A diameter combination with the lowest system cost is selected using cost function and used as a final optimal calculation result. A program in Visual Basic 6.0 was created based on this enumeration algorithm and adopted in the design of stormwater drainage system. The results show that the enumeration algorithm is a practical global optimization method, and it can be used for optimization of stormwater drainage system in complicated terrain.
