The invention provides a concrete filling geotextile bag, which comprises a main body geotextile bag, wherein the main body geotextile bag is sewed by high-intensity geotechnical cloth, a plurality of groups of ribbed belts are vertically woven on the geotechnical cloth, the ribbed belts are arranged at the inner side of the main body geotextile bag and are respectively woven on the geotechnical cloth arranged at the two sides, each group of ribbed belts comprise 1 to 3 ribbed yarns, floating wire parts for controlling the thickness of the main body geotextile bag are also arranged on each ribbed belt, and the floating wire parts are arranged in a way with the intervals being 3 to 5cm in the vertical direction of each ribbed belt. The concrete filling geotextile bag has the advantages that the shape and the dimension of the filled main body geotextile bag can be better controlled according to construction requirements, and reinforcing belts and transition yarns with different telescopic performance from the peripheral main body yarns are arranged in the main body geotextile bag, so that obviously different concave marks are formed in the filled main body geotextile bag, and the basic bottom surface of the main body geotextile bag can be naturally and tightly pasted with an uneven digging surface.
