Abstract:It delt with the probabilistic characteristics of strength indexes of silty clay in Taiyuan, and studied more thoroughly the correlation between the strength indexes of different tests. The variability coefficients of strength indexes for Taiyuan silty clay were compiled statistic on, then some chang laws were drawn out. And also the paper built the distribution for strength indexes of Taiyuan silty clay, studied the correlation between physical and strength indexes, and got some empirical equations. There is higher variability for strength indexes of silty clay in Taiyuan. The Bata mathematical distribution model is fitter for strength than the normal distribution model. There is remarkable defferentce between strength indexes by deffrent test methods, which need urgently be handled probabilisticly for geotechnical engineering, but there is high correlation between them.
Keywords:silty clay  strength indexes  variability coefficient  probabilistic distribution
