[0021] The present invention will be further described below in conjunction with the accompanying drawings.
[0022] Such as figure 2 , 3 As shown, a fully permeable pavement structure suitable for large slopes includes a permeable surface layer 1, a water storage base layer 2, a subbase layer 3, a geotextile 5 and a soil foundation 4. The soil foundation 4 is a ladder structure, and each step surface of the soil foundation 4 is laid with a subbase 3, and all the subbase 3 also form a ladder structure; the ratio of the width and length of the soil foundation 4 of each permeable roadbed unit is equal to the road surface slope; The soil foundation 4 is a natural compacted foundation, and the subbase 3 is a water-permeable graded crushed stone. The geotextile 5 is placed between the subbase 3 and the soil foundation 4, and the geotextile 5 is a permeable geogrid cloth, which can not only improve the bearing capacity of the soil, but also play a filter effect to prevent the soi...
