The utility model provides a three-dimensional shock absorption and isolation bridge support which comprises a lower support plate and a base plate, and an annular spring used for vertical shock absorption and isolation is connected between the lower support plate and the base plate in series on the whole, the support is any one of a plate-type rubber support, a basin-type rubber support, a common spherical support, a hyperboloid spherical seismic mitigation and isolation support and a friction pendulum spherical seismic mitigation and isolation support; for example, when the support is a double-curved-surface spherical seismic mitigation and isolation support, the double-curved-surface spherical seismic mitigation and isolation support comprises an upper base plate, a middle base plate and a lower base plate which are sequentially arranged from top to bottom, spherical friction pairs are arranged between the upper base plate and the middle base plate, and spherical friction pairs are arranged between the mid
