基于防洪安全影响的河道采砂场设置方案比选研究

Comparison and selection of river mining setting schemes based on the influence of flood control safety

随着河沙需求量的不断增长,无序采砂行为对河道防洪安全以及河势的影响日渐突出,选择合理的采砂场设计方案具有重要的理论和实践意义。文章利用数值模拟的方法,对大凌河干流某采砂场的设计方案进行对比研究,综合研究结果,推荐全封闭采砂方案为某采砂场的设计方案。

With the increasing demand of river sediment,the influence of disordered sand mining on flood control safety and river regime is becoming increasingly prominent.It is of great theoretical and practical significance to select a reasonable sand mining design scheme.In this paper,the numerical simulation method is used to make a comparative study on the design scheme of a sand quarry in the mainstream of Dalinghe River.Based on the research results,the fully enclosed sand mining scheme is recommended as the design scheme of a sand quarry.
