Title: STUDY ON ENGINEERING CHARACTERISTICS OF SILTY CLAY UNDER WATER IN LOWER REACH OF YANGTZE RIVER
Abstract: Based on large numbers of geotechnical testst,he engineering characteristics of silty clay under water in the foundation of Suzhou—Nantong large bridge in lower reach of Yangtze River,Jiangsu Province,China,was studied.It was found that the variation coefficients of silty clay parameters were different.The variation coefficients of specific gravity,natural density,saturation of soil grain were smaller,the variation coefficients of natural water content,natural void ratio,and liquid limit were moderate;and those of plastic limit,compressive module,compressive coefficient,coherent strength,inner friction angle,the blow counts of standard penetration test(SPT) were greater.For physical parameters,there didn′t exist correlativity between liquid limit and natural water content,the correlativity between plastic limit and natural water content was better;and the correlativity between natural void ratio and natural water content,natural density were very good.For deformation parameters,the correlativity between compressive module,compressive coefficient and natural void ratio,natural water content,natural density were better;and the correlativity coefficients were greater than 0.87.There didn′t exist correlativity between compressive coefficient and liquid limit,but there was correlativity between compressive coefficient and plastic limit;and the correlativity coefficient was 0.611 09.The results indicate that the statistical analysis of geotechnical test data is an important method for the study of soil engineering characteristics.
