摘要
以太原地区典型土层——粉质粘土为代表 ,根据 2 0个工程的勘察资料及室内一系列强度试验 ,对该地区粉质粘土工程性质指标的概率统计特征进行了研究探索 ,得出了其土性指标变异系数的变化规律和土层的变异类型 ,建立了其设计参数的 Beta分布概率模型 。
The paper,based on statistics analyses of the observed data,delt with the statistic characteristics of engineering of silty clay in Taiyuan,and came to some practical results.The statistic data for research were extracted from the engineering geologic investigation reports of 20 important buildings and 15 groups of strength tests in lab.The variability coefficients of physical mechanical indexes for Taiyuan silty clay were compiled on,then some change laws were drawn out.The Beta distribution of the mathematical models for module of compresibility and shear strength index of silty clay was built and the correlation between indexes was expressed by empirical equations.
