在平原圩区,排水干道水位的控制,不仅关系到农田排水效果,而且影响到排水系统的工程投资及其运行费用,因而是圩区除涝规划中需要解决的重要问题之一。本文应用动态规划理论,探讨了一个解决排水干道水位控制优化问题的方法,并附有计算实例。计算成果表明该法是可行的。 In the plains polders, the control of the water level of drainage channels not only affects the drainage effect of farmland, but also affects the investment of the drainage system and its operating costs, which is one of the important issues to be solved in the planning of waterlogging drainage in polder areas. In this paper, the dynamic programming theory is used to discuss a method to solve the problem of drainage control of drainage culverts, with the calculation examples. The calculation results show that this method is feasible.
