基于河道断面经济优化设计探究

Analysis of Economic Optimization Design for River Section

为最大化实现城市河道治理的经济效益,文章以辽宁省某河道为例,在详细分析断面约束条件及参数特征的基础上,利用遗传算法优化设计了最佳方案。研究表明:优化设计方案具有良好的可行性与适用性,文章提出的经济优化设计方法能够针对不同的目标和约束条件修正调整模型;在河道治理中利用遗传算法的优化设计方法具有较高的准确性与可靠性,研究方法可为制定河道设计方案提供一种新的思路。

In order to realize the economic benefits of urban river course regulation,taking a river course in Liaoning Province as an example,this paper optimized and designed the optimal scheme based on the detailed analysis of cross-section constraints and parameter characteristics with the genetic algorithm.The results show that the optimal design scheme has good feasibility and applicability and can modify and adjust the model according to different objectives and constraints. The optimal design method based on genetic algorithm has higher accuracy and reliability in river regulation project,and the research method will provide a thinking new way to formulate the river design scheme.
