摘要: 砂-粉混合料是自然界和岩土工程中常见的非均质土,密实程度、应力水平和细粒含量等因素对其颗粒接触状态和力学性能具有显著影响。为了能够较为全面地描述砂-粉混合料在细粒含量阈值内的复杂力学特性(FCAbstract: Sand-silt mixtures, as common heterogeneous soils, are ubiquitous in nature and geotechnical engineering, and their particle contact state and mechanical properties are significantly affected by factors such as density, stress level, and fines content. In order to comprehensively describe the complex mechanical properties of sand-silt mixtures within the fines content threshold (FC
