The invention relates to the technical field of civil engineering and discloses a landslide-preventing slope protection soil filling structure. The landslide-preventing slope protection soil filling structure comprises one or more layers of geotechnical cloth layers arranged in the transverse direction and soil filling layers, wherein the number of the soil filling layers corresponds to that of the geotechnical cloth layers, and the geotechnical cloth layers and the soil filling layers are arranged alternately. The geotechnical cloth layers are adopted so that the slope protection body soil filling layers can be arranged at intervals. Strong tensile performance of geotechnical cloth is adopted so that the relative sliding trend between every two adjacent soil filling layers can be effectively reduced. An edge wrapping structure wrapping the corresponding soil filling layer is formed on the edge of the soil filling layer by every two adjacent geotechnical cloth layers. Periphery constraint is generated on the soil filling layers, stress of the soil filling layers is concentrated, the phenomenon that the soil filling layers move randomly in the slope protection direction of a slope protection body and press a slope protection component can be avoided effectively, and the overall structural stability of the slope protection body is improved. Pulling beams are additionally arranged in the geotechnical cloth layers, pulling teeth are arranged on the pulling beams, the slope protection component can be firmly attached to the slope protection position of the slope protection body due to the interaction pulling force formed between connection of the pulling teeth and slope protection component and connection between the pulling beams and the slope protection component, and the slope protection body can be further protected against landslides.
