摘　　要：通过收集绍兴平原地区150个静力触探孔测试数据与工程勘察资料,总结了绍兴市平原地区典型静力触探曲线随深度变化规律,确定了杂填土、淤泥质粉质黏土、粉质黏土、黏土和粉细砂层的判别特征。通过对静力触探探头获取的数据进行统计和分析,揭示了各土层锥尖阻力、侧摩阻力和摩阻比的值域范围,静力触探参数与黏性土的液性指数、压缩模量、黏聚力和桩侧阻力的拟合公式,为绍兴平原地区的土层划分与参数评价提供依据。150 static contact test data and corresponding engineering investigation data were collected to summarize the vari-ation rules of soil parameters of typical stratums in Shaoxing Plain area.The variation pattern of typical static cone penetration curves with depth was summarized,the determination characteristics of mixed fill,muddy silty,silty clay,clay and fine sand layers was de-termined.Through the statistics and analysis of the data obtained by CPT,the ranges of cone tip resistance,side friction resistance and friction ratio were specified.The correlation equations between the static penetration parameters and the liquid index,compression modulus,cohesion,and pile side resistance of cohesive soil were put forward.The conclusions provide a basis for soil division and parameter evaluation in Shaoxing Plain area.
