Using the proposed evaluating method, the variation of non-uniformity of the mean effective stress and the stress ratio and their distribution along the radius direction are discussed and explained in detail. It is found that there are several peak for the non-uniformity of mean effective stress but only one peak for the stress ratio. As the apparent shear strain increases, the distribution of mean effective stress and stress ratio along the radius also varies and the outer is always faster than the inner.
