Abstract:: The polymer soil stabilizer was used to protect the soil slope surface ecologically. The strength, anti-erosion and vegetation growth of soil modified with polymer soil stabilizer were evaluated in the laboratory. The ecological slope protection mechanism was analyzed by the test results and microscopic scanning. Engineering example application was carried out to prove the ecological slope protection effect. The results show that the strength and anti-erosion of soil are improved by polymer soil stabilizer, and the vegetation growth is promoted; the ecological slope protection mechanism of polymer soil stabilizer is that a mesh membrane structure of soil particle on slope surface is formed by the wrapping of polymer soil stabilizer, to improve the strength and anti-erosion of soil and provide a well growth environment, so as to achieve the effect of the ecological slope protection; the feasibility of ecological slope protection with polymer soil stabilizer is verified by engineering example, therefore, this method can be considered as an effective solution for the soil slope surface treatment.
