In view of the landslide caused by rainfall, a composite structure of seepage guidance and anchorage is proposed. Pervious concrete is used as anchorage cementing material to realize the function of permeability and anchorage. The permeability coefficient, bonding force and cohesion of soil interface were tested. Summarizing the rules of these parameters, we can see that it is feasible to use pervious concrete to realize the composite functional structure. When the porosity is 18%, the comprehensive effect is better. The numerical analysis shows that the composite structure can make the rainfall infiltration line rise slowly and the rock and soil deteriorate slowly, which is beneficial to the stability of the slope. After the rain stops, the characteristics of water and soil in the slope can be restored quickly.
