The utility model belongs to building structures, and particularly relates to a novel main cable anchoring system of a suspension bridge and unit pieces of the novel main cable anchoring system. The system comprises a plurality of anchoring plates connected with main cable strands, wherein each anchoring plate is formed by one or more distributive force transmitting type anchoring system unit pieces according to the different numbers of the anchoring strands; each distributive force transmitting type anchoring system unit piece comprises three parts, namely an anchor box, a pull rod and an anchoring area which are connected in sequence; the anchor boxes are connected with the main cable strands; and the anchoring areas are connected with anchor body concrete. A plurality of rows of reinforced concrete tenon shear connectors are distributed in the anchoring areas, so that the tension of the strands are successively distributed and dispersed, and gradually transferred to the anchor body concrete; and owing to the high ductility of the reinforced concrete tenon shear connectors and the small-size rigid bearing plates arranged at the rear ends of the anchoring areas, structural safety margin is improved. The distributive force transmitting type main cable anchoring system disclosed by the utility model has the advantages that stress concentration of the concrete of the anchoring system and the anchoring areas is greatly reduced, the main cable anchoring and force transmitting areas are enlarged, the performance is reliable and the durability is high.
