[0002] The main process of ecological slope protection is to protect and reinforce the surface of the slope by planting plants after the excavation slope is formed, and utilizing the interaction between plants and rocks and soil (root anchoring effect). This method of slope protection can not only meet the requirements for slope surface stability, but also restore the damaged natural ecological environment. It is an effective means of slope protection and consolidation.

[0039] Among them, the slope of the first slope 1 is m≥1.5, and three layers of compacted soil layers 2 are arranged on the slope surface of the first slope 1. The bottom layer is plain soil with a compaction coefficient ≥0.90, the middle layer is compacted plain soil with a thickness of 400mm and a compaction coefficient ≥0.92, and the upper layer is clay with a thickness of 400mm and a compaction coefficient ≥0.90. After the compacted soil layer 2 is compacted, an expansion joint 201 is arranged every 10m on the compacted soil layer 2, with a width of 200mm, and the joints are filled with asphalt fir boards.

[0040] The nutrient nonwoven fabric 3 is a composite structure of a filter layer and a nutrient layer, with a specification of 300g / m2 to 400g / m2, and is laid between the compacted soil layer 2 of the bottom layer and the first slope 1.
