安阳地区粉质粘土相关性及承载力研究

Research on correlation and bearing capacity of silty clay in Anyang region

结合安阳地区典型岩土工程勘察实例,基于岩土工程数理统计理论对研究区域内浅层粉质粘土物理力学参数和承载力进行研究。结果表明:研究区域内浅层粉质粘土物理参数的变异性小、相关性显著,力学参数的变异性相对较大、相关性不显著;浅层粉质粘土地层承载力与标准贯入实验值、静力触探实验值以及土工试验参数间呈近视线性关系,地层承载力地域性经验公式与实际承载力具有较高的符合性。研究成果可为区域性地基基础可靠性设计和承载力的确定提供必要的参考价值。

Combined with the engineering practice of typical rock and soil in Anyang area, mechanical parameters and bearing capacity of the regional silty clay were studied by basing on mathematical sta- tistic theory of rock and soil engineering to study the physical. The research show that： within the study area of shallow silty clay, the variation of the physical parameters is small, the correlation of the physical parameters is conspicuous, the variation of the mechanical parameters is large, and the cor- relation of the mechanical parameters is not conspicuous. There is a linear relationship between the standard penetration test values, static cone penetration test values, and soil test parameters values with the bearing capacity of the shallow sihy clay. The regional empirical formulas of bearing capacity and the actual bearing capacity have higher uniformity. The research results can provide necessary references for the reliable design of regional foundation and determination of hearin~, , ;t,,
