摘要
堤防工程在我国的防洪工作中起着十分重要的作用,要想保证堤防安全运行,基本条件是要保证堤脚岸滩不被冲刷。本文选取了一种新型的岸滩保护措施——模袋排帘,用Flow3D建立数值模型的方法来研究其周围流场变化,以此分析泥沙的冲淤情况,再进一步分析模袋排帘在堤防工程中可以产生的保护效果。结果表明,模袋排帘周围的水动力变化有利于泥沙沉降,对岸滩的保护作用较为明显,适合用于堤防保护工程。
Dike projects play an important role in flood prevention in our country, and the basic requirement is to protect the toes of the dike from being washed away. In this paper, a new bank-protection measure,geotextile mattress with sloping curtain（GMSC）, was proposed. The flow field around GMSC was studied with the numerical models established by Flow3 D, which was used to analyze the sediment scouring and silting situation and the protection effect of GMSC in dike projects. Results showed that the hydrodynamic changes were beneficial to sediment deposition and bank protection, and it was suitable for dike protection projects.
