In order to scientifically and reasonably evaluate and select the quality and effect of ecological slope protection construction project and the structural form of ecological slope protection, this paper mainly studies nanomontmorillonite modified fly ash ecological slope protection material and its preparation method and related applications. The nanomontmorillonite modified fly ash ecological slope protection material and its application in this paper are based on nanomontmorillonite modified fly ash as the basic carrier, and the pore structure is used to plant grass for slope protection to achieve the purpose of ecological slope protection. Firstly, the nanomontmorillonite modified fly ash ecological slope protection material was prepared through the selection of raw materials, the mix ratio design, and the reasonable selection of the preparation process, and the range analysis method was used to optimize the mix ratio of nanomontmorillonite modified fly ash. By reasonable selection of alkali-reducing measures, selection of slope protection vegetation, preparation of planting substrates, and research on phytobiology, through experimental analysis, we obtained nanomontmorillonite modified fly ash with high strength and good water permeability and alkalinity in the pores to meet the requirements of plant growth ecological slope protection materials. Finally, through engineering practice, we explored the construction method of nanomontmorillonite modified fly ash ecological slope protection material and obtained good ecological slope protection benefits. The experimental data show that, for dispersive soil, when the degree of compaction is 80%, the compressive modulus of the soil is 3.46 MPa; when the degree of compaction is 86%, the compressive modulus of the soil becomes 4.51 MPa, an increase of 46.57%. The experimental results show that the nanomontmorillonite modified fly ash ecological slope protection material can help the soil become more compact.
