| Abstract: | According to mass of the testing data of clay silt and silty clay in Beijing and based on mathematical statistic theory,this paper analyzes statistically the physical mechanics indexes,discusses the distribution features of clay indexes and their differentiation.By means of the linear regress method,this paper studies the interaction of indexes and attains the corresponding experiential formula with the results offering a foundational data for "engineering construction layer in Beijing ". |
