The Gabion and the flexible net are considered to be the new trend in the landslide control project.Based on debris flow model test

this paper gives up one guest and one flexible net

which are formed by guest-flexible composite structure.Through analysis the following conclusions are drawn:（1）The hindering effect of Gabion-flexible net structure of debris flow is obvious

it not only has the advantages of rapid drainage

but also solid material can be blocked.（2）The porosity of blocked structure has sorting effect for source of debris flow.According to the difference types of debris flow

blocked structure can be adjusted to achieve the best block effect.（3）The stress at the bottom of hindered structure is larger.The impact gradually decreases from the bottom to the top.The gap of the impact in the different positions of the first hindered structure（flexible net）is very wide.The gap of the impact on the different positions of the second hindered structure（Gabion）is very small.
