The invention discloses an anti-explosion and anti-impact protective device for a circular pier column and relates to the technical field of bridge engineering and building structures. The anti-explosion and anti-impact effects can be achieved in the mode that a rigid protection structure is filled with a flexible combination structure. The rigid structure of the protective device is designed in the mode that an arc-shaped hollow structure formed by combination splicing of an externally-arranged cambered plate and an internally-arranged cambered plate is additionally arranged outside a core structural column. The arc-shaped hollow structure is filled with combined steel pipes formed by means of the method that a plurality of same steel pipes with the small pipe diameter are externally tangent to steel pipes with the large diameters, foamed aluminum composite steel pipes and anti-extruding dense small steel pipes; and gaps outside the combined steel pipes, the composite steel pipes andthe anti-extruding dense
