The invention discloses a concrete anisotropic multi-scale damage variable quantization method. The method comprises the following steps of extracting coordinates of all damage points reaching a critical damage value in a microstructure, and calculating out a uniform part, namely, a distributed damage tensor, of a multi-scale damage variable for non damage points; setting projection coordinate axes at angle intervals in the microstructure, performing equal-interval division on each projection coordinate axis, setting 2n gaps, and traversing all the projection coordinate axes to obtain relativecoordinates of the damage points on the projection coordinate axes; and according to the relative coordinates, calculating out occupied gap numbers of the damage points on the projection coordinate axes, obtaining effective gaps on the projection coordinate axes, then determining maximum and minimum damage direction angles and area missing degrees of corresponding directions, and finally obtaining an anisotropic multi-sc
