“…As demonstrated by equations (7) and (8), when the particle size distribution of granular materials satisfies strict fractal distribution and statistical fractal distribution, Cu/Cc and D have functional relationships. In terms of characterizing the particle size distribution of rockfill, transition material, and other granular materials, D is equivalent to Cu and Cc.…”

“…The particle size distribution of a granular material is commonly expressed by its particle grading curve and the related characteristic parameters of uniformity coefficient Cu and curvature coefficient Cc. 7 At present, the evaluation of particle size distribution is mainly based on engineering experience; however, a series of problems arise in field applications such as broad evaluation standards and strong human subjectivity. In view of this, this article proposes a new method for evaluating the particle size distribution of granular blasting materials based on the fractal theory, which might provide several significant 1 implications for practical applications from a more sound theoretical basis.…”

The particle size distribution of granular blasting materials has a vital influence on the filling quality of earth-rockfill dams. The engineering experience-based method used to evaluate the particle size distribution has shortcomings at both the theoretical and practical aspects. This article proposes a new evaluation method based on the fractal theory. Grading sieve tests on granular materials, mass fractal analysis of particle size distribution, and a probability distribution model test of the characteristic parameters are used to revise the functional relationships between the fractal dimension D and the uniformity coefficient/curvature coefficient ( Cu/ Cc) of the grading curve. The feasibility of using D to evaluate the particle size distribution and the optimal fine grain content is then analyzed and determined. According to the results, the geometric shapes of the granular blasting materials have fractal characteristics, and their particle size distribution has a fractal distribution. The ranges of D where the rockfill and transition materials have a good particle size distribution are D = 2.254–2.529 and D = 2.358–2.559, corresponding to optimal fine grain content of 1.953%–11.805% and 10.268%–23.123%, respectively. Fractal dimension has a solid theoretical basis and strong practical applicability as an evaluation index for the particle size distribution of granular blasting materials.

“…is means that there is some relationship between K 0 and GSD of sandy gravel. On the other hand, for a given in situ sandy gravel, if the preparation technique is the same, the GSD of test specimen are principally determined by d M [26], Advances in Civil Engineering and therefore, there may be some relationship of K 0 and d M for test specimens prepared by the same preparation technique. If the relationship of K 0 and d M can be obtained, the K 0 behavior of the sandy gravel in situ can be extrapolated by using the K 0 − d M relation.…”

To investigate the scale effect on at-rest earth pressure coefficient K 0 for sandy gravel, a number of K 0 tests for sandy gravel were performed by using a new-developed large-size K 0 apparatus. e test samples with different maximum particle size d M are prepared by different techniques, and the scale effect on K 0 behavior of sandy gravels is investigated. It is found that the vertical stress σ v , preparation technique and d M all have some influence on the value of K 0 for the tested sandy gravels. Since different d M or preparation techniques all induce the scale effect, the scale effect on K 0 of sandy gravel can not be ignored. Based on the test data of sandy gravel, a description of K 0 considering scale effect as well as σ v is proposed and an approach to predict the K 0 behavior of sandy gravel in situ is obtained. Furthermore, the accuracy and applicability of the approach is verified.
