【摘要】 本文以保山盆地软土、次生红黏土、膨胀土和粉土为研究对象，对不同成因特殊土主要物理力学指标进行相关性和差异性分析。研究结果表明：4种不同成因类型特殊土的天然含水率、孔隙比、湿密度之间均具有显著的相关性，次生红黏土、膨胀土和粉土压缩模量与压缩系数之间存在显著的指数相关性，物理指标与力学指标间拟合效果均一般；4种不同成因类型特殊土的物理力学指标变异系数总体较高，与物理指标相比，力学指标变异系数变化较大，离散程度更大。更多还原

【Abstract】 This paper investigates the soft soil, secondary red clay, expansive soil and silt in the Baoshan Basin, comparative analyses of correlations and variations in key physical-mechanical indices were performed for the genetically distinct special soils. The results demonstrate: Significant correlations exist among natural moisture content, void ratio and wet density for all four special soils.Exponential correlations were identified between compression modulus and compression coefficient for secondary red clay, expansive soil and silt, while physical-mechanical index correlations generally exhibited limited fitting accuracy. The coefficients of variation for physical-mechanical indices were notably high across all soils, with mechanical indices displaying greater variability and data dispersion compared to physical indices.更多还原
