Novel unsaturated cohesive soil slope reinforcing mode
The invention discloses a novel unsaturated cohesive soil slope reinforcing mode, and belongs to the technical field of slope stabilization. The slope is reinforced by compounding the alfalfa and the nettle fiber net pad, and compared with a traditional concrete retaining wall, the slope retaining wall has higher environmental protection value. The slope protection mode is suitable for an unsaturated cohesive soil material side slope, and in the initial vegetation forming stage, nettle fiber nets are mainly used for reinforcing a slope body; in the rainy season, the plants can change the permeability of the soil body, for example, the Reynolds number and Froude number of the slope soil body are changed, the water flow shear strength of the soil body material can be improved, and the flow erodibility can be reduced; meanwhile, the plant fiber geonet can reduce soil loss in a series of event processes such as rainfall to a great extent, and rainwater splashing can be reduced in the scouring process of rainwater and the like, so that the surface soil body can be protected, erosion of the surface soil body is reduced, and finally the soil loss of the side slope is reduced.
本发明公开了一种新型非饱和粘性土边坡加固方式，属于边坡的稳定技术领域。本发明采用苜蓿草与荨麻纤维网垫复合进行边坡加固，与传统混凝土挡土墙相比具有更高的环境保护价值。该护坡方式适用于非饱和粘性土材料边坡，在植被形成初期以荨麻纤维网为主，对坡体进行加固；在雨季过程中，植物能够改变土体的渗透性，如改变边坡土体的雷诺数与弗劳德数，并且能够提高土体材料的水流抗剪强度，能够降低流动侵蚀力；与此同时，植物纤维土工网能够在很大程度上减小降雨等一系列事件过程中的土壤损失，在雨水等冲刷过程中，会减少雨水飞溅，从而能够保护表层土体，减少表层土体的侵蚀，最终降低边坡的土壤损失。
