Building an ecological slope protection system in the drawdown area of Three Gorges reservoir bank is imperative. Multiple anti-slide bearings were fixed on the riverside slope of the fluctuating zone of the reservoir area, and antioverturning boards were fixed on the bearings. All the anti-slide bearings, which were placed in the same height position in the transverse direction of the riverside slope, were connected by steel bars to form the backbone slip in the longitudinal direction. Two neighboring backbone slips in the transverse direction formed a groove. In the grooves, fill layer, water layer, fermented silt filling, and soil layer were paved sequentially from bottom to top. The results show that the slope protection system effectively manages the sludge, wastewater, and fluctuating zone treatments as one body; reduces energy consumption; saves energy; and benefits the environment.
