The invention discloses a sludge solidified soil homogeneity evaluation method which comprises the following steps: S1, acquiring the pH value pH0 of solidified soil under the condition that sludge muck and a cementing material are fully mixed in an ideal state, a reference mass value M0 after water erosion resistance and unconfined compressive strength C0 as reference values; s2, under the condition that stirring time is set on a construction site, the sludge muck is stirred, and the characteristic pH value pH1, the characteristic mass value M1 and the characteristic strength value C1 of an actual soil sample are measured according to the same method for obtaining the reference value and serve as characteristic values; s3, calculating the homogenization coefficient U of the solidified soil according to the following formula: U = delta1S + delta2Z + delta3Q; and S4, determining the homogeneity of the solidified soil. The method has the advantage that the uniformity of the solidified soil of the sludge residue
