摘要: 粗粒料的级配对其物理力学性质具有重要影响。土体的级配通常用级配曲线来表示,级配方程则是对土体级配曲线的定量描述。利用土的连续级配方程,对各种粗粒料级配的适用性进行了验证,进一步总结了土石坝工程中粗粒料级配参数的常用取值范围;同时,分析了利用该方程进行粗粒料配料计算的实用性。主要结论如下:粗粒料的级配参数常用取值范围集中在-2

Abstract: The properties of the coarse-grained soil are significantly affected by its gradation. The gradation of the soil is usually descripted by the particle size distribution curve (PSD), and the gradation equation is a quantitative description for the PSD. A continuous gradation equation was developed in this paper, and its applicability was verified by many PSDs of the rockfill material, transition material and filter material used in earth-rock dams. Furthermore, the range of gradation parameters of the coarse-grained soil was summarized, and the applicability of the gradation equation was analyzed. The main conclusions are as follows: The commonly used gradation parameters of coarse-grained soils are in the range of -2

Key words: gradation equation, coarse-grained soil, earth-rock dam, reduced scale, calculation of ingredients
