摘要
通过大量的土工试验,对昆明市硬壳层黏土力学与物理参数间的相关关系,特别是压缩模量、内聚力、内摩擦角φ与各物理参数相关关系进行统计分析,并给出相应的数学回归方程式和相关系数。结果表明:昆明市区上覆硬壳层黏土的压缩模量Es与液性指数、塑限、孔隙比、塑性指数有较好的相关关系。内聚力与液性指数、塑限、孔隙比有较好的统计相关关系。内摩擦角与重力密度有较好的一元线性相关关系,与重力密度、塑性指数、土粒比重有较好的多元线性相关关系。
Through a lot of soil test, the relationship between hard shell layer of clay mechanical and physical parameters in Kunming has been made statistical analysis, especially the relationship of compression modulus, cohesion, internal friction angle and the correlation of various physical parameters, and the appropriate mathematicalregression equation and correlation coefficient have been given. There are concrete manifestation of the following aspects. In Kunming, the clay of the overlying crust layer compression modulus Es and liquid index, plastic limit, the void ratio and plasticity index is showed to be better correlation. The statistical correlation is illustrated to be better between cohesion and liquid index, plastic limit and void ratio. The angle of internal friction and gravity den- sity is displaied to have a good linear correlation, and the angle of internal friction, gravity densityplasticity index, and specific gravity is proved to have a better multiple linear correlation.
