河道整治岸坡护砌方案的优选研究

Study on Optimization of Bank Slope Protection Plan for River Regulation

科学、合理的岸坡护砌方案是实现河道治理预期目标的重要基础和条件。文章根据辽宁省某小流域河道治理工程实际状况初步拟定了3种不同的护砌方案。然后基于层次分析法构建了方案优选决策模型,通过构造判断矩阵、一致性检验与权重计算,最终选出最佳的河道整治方案即浆砌石结合植草砖方案,它可为河道生态整治措施及治理方案的优选决策提供一定参考依据。

Scientific and reasonable bank slope protection scheme is important foundation and condition for realizing the expected goal of river regulation.In this paper, three kinds of various protection plans are proposed preliminarily according to actual situation of river regulation project in a small river basin in Liaoning Province.Afterwards, the scheme optimization decision model was established based on AHP method, an optimal river regulation plan is selected finally by the judge matrix construction, consistency check and weight calculation, that is, wet masonry combined with grass planting brick scheme, which will supply a certain accordance for ecological regulation measures of river course and optimal decision of regulation plan.
