引用新型的柔性拦阻网和格宾结构被认为是泥石流治理工程的新趋势。基于泥石流模型试验,设置了一道格宾和一道柔性网,组成了格宾-柔性网组合结构,通过分析拦阻结构迎水面的冲击力和被拦阻物源的级配组成,结果表明:(1)泥石流格宾-柔性网组合的拦阻效果明显,既具有快速排水的优点,也具有将固体物质拦截的特点;(2)拦阻结构的孔隙率对被拦截物源的粒径有分选作用,根据不同的泥石流类型,可以调整拦挡结构的孔隙率,以达到最好的拦挡效果;(3)拦阻结构底部受力比较大,冲击力从底部向上逐渐减小。第一道拦阻结构(柔性网)上不同位置处的冲击力相差最大,第二道拦阻结构(格宾)不同位置冲击力相差较小。
Reference to the new type of flexible barrier network and Graben structure is considered a new trend of debris flow control engineering. Based on the debris flow model test, a gabion and a flexible net were set up to form the Gabing - flexible net composite structure. The impact force of the water blocking structure and the gradation of the obstructed material source were analyzed. The results showed that: (1) Debris flow Graben - flexible mesh combination blocking effect is obvious, both with the advantages of rapid drainage, but also has the characteristics of intercepting solid matter; (2) blocking structure of the porosity of the source material was intercepted particle size sorting, according to Different types of debris flow, you can adjust the porosity of the block structure in order to achieve the best blocking effect; (3) blocking the bottom of the structure by a relatively large force, the impact from the bottom up gradually decreases. The first barrier structure (flexible net) on the impact of different locations at the maximum difference, the second barrier structure (Gabing) different locations with a small difference in impact.
