Based on the results of triaxial tests for sands of various particle-size distribution, a statistical assessment of the dependence of Reynolds dilatancy on the parameters of density and stress state was carried out. An improved model, which takes into account the dependence of the dilatancy angle on the current and residual void ratios and the effective stress level, is proposed. Recommendations are given on the use of research results in the practice of geotechnical calculations.

三轴压缩条件下无粘性土的膨胀性试验研究

根据各种粒径分布的砂土的三轴试验结果，对雷诺膨胀率对密度和应力状态参数的依赖性进行了统计评估。提出了一种改进的模型，该模型考虑了剪胀角对电流和剩余空隙率以及有效应力水平的依赖性。提出了在岩土计算实践中使用研究结果的建议。
