The invention provides a function separation type energy-dissipation and shock-absorption support provided with a self-restoration friction rope and belongs to the field of seismic prevention of building structures such as bridges. The function separation type energy-dissipation and shock-absorption support is placed between a girder body and a fixed pier. According to the structure of each support, anchor legs are fixed to the fixed pier; a friction shaft is fixed between the two anchor legs; girder connecting pieces and limiting pins are fixed to the girder body; one end of each reset spring is connected with the corresponding girder body connecting piece, and the other end of each reset spring is connected with the corresponding anchor leg; the friction rope is wound on the friction shaft by a plurality of circles, and the two ends of the friction rope are connected to the connecting pieces correspondingly after pre-tightening force is applied to the friction rope; and the reset springs and the friction rope are perpendicular to the axis of the friction shaft. The support can meet normal using requirements; a shock absorption and insulation function can also be achieved when a strong earthquake occurs, the situation that a conventional shock-absorption and shock-insulation support is damaged due to the fact that the relative displacement is too large when the earthquake occurs is effectively prevented, the capacity of the fixed pier is protected, and the anti-seismic property of a continuous girder bridge is improved; a good post-earthquake self-restoration function is achieved under the effect of earthquake complementary energy after the earthquake peak value; and the structure is simple, and the manufacturing cost is low.
