The invention discloses a method and a device for measuring chlorine ion content distribution in a bridge pier column concrete member. The method comprises the following steps: acquiring first pier column concrete, and pretreating to obtain second pier column concrete; a sampling point on second pier column concrete is designed; determining the sampling volume according to the maximum particle size of the selected coarse aggregate; determining sampling width according to the outer diameter of the grinding head; the sampling length is determined according to the first pier column concrete height; calculating the sampling depth according to the sampling volume, the sampling height and the sampling length; performing radial grinding on the sampling points according to the sampling parameters to obtain a concrete sample; measuring the chlorine ion content of the sample; calculating to obtain sample coordinates according to the sampling parameters and the sampling points; and processing the sample coordinates and
