Abstract

The maximum and minimum void ratios define the loosest and densest conditions of a granular soil. Correlations with some granulometric properties of soil are of interest for practical applications, but the experimental procedure to determine these variables can be time consuming. In this work the influence of the grain size distribution on the maximum and minimum void ratios is investigated. Twenty different granular soils with varying grain size distributions were prepared and tested. The experimental results, together with a compilation of 56 additional results reported in the literature, are statistically analysed. The analysis is conducted to examine the influence of some granulometric properties (D10, D30 and D60) on the maximum and minimum void ratios. As a result, some correlations considering the aforementioned variables are proposed. Subsequently, it is shown that the proposed correlations have better agreement with the experimental data than other proposals reported in the literature. The paper ends with some concluding remarks.

粒径分布对颗粒土最大、最小空隙比的影响

孔隙率的最大值和最小值决定了颗粒土最疏松和最致密的状态。在实际应用中，与一些土壤粒度特性的相关性是有意义的，但是确定这些变量的实验过程可能是耗时的。本文研究了晶粒尺寸分布对最大和最小空隙比的影响。制备了20种不同粒径分布的颗粒土并进行了试验。实验结果，连同56额外的结果汇编在文献中报道，进行统计分析。分析了一些颗粒性能(D10、D30和D60)对最大和最小孔隙比的影响。因此，提出了考虑上述变量的一些相关性。随后，研究表明，所提出的相关性比文献中报道的其他建议更符合实验数据。论文以结束语结尾。
