摘要:
针对土质边坡坡面稳定性问题,从土体改性机理出发,采用高分子稳定剂对土质坡面进行生态护坡。对自主研制的高分子稳定剂改性土的强度、抗冲刷性和植被生长等进行了室内评价,通过室内试验和微观扫描深入分析了高分子稳定剂的生态护坡机理,并通过工程实例应用进一步验证了高分子稳定剂的生态护坡效果。结果表明:高分子稳定剂可以在较大程度上提高土体的强度和抗冲刷性,同时可以促进植被的生长;高分子稳定剂生态护坡机理是通过包裹土质边坡坡面的土颗粒形成网状膜结构,提高土体的强度和抗冲刷性等性能,给坡面植被提供良好的生长环境,从而达到生态护坡的效果;工程实例验证了高分子稳定剂应用于土质边坡生态护坡的可行性,为土质边坡坡面治理提供了一条有效的解决途径。
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.
