【摘要】 使用自行研制的GZZ-1型共振柱试验机对南京及其邻近地区漫滩相成因的淤泥质粉质粘土、粉质粘土、粘土、粉土、互层土和粉细砂等新近沉积土进行了大量的共振柱试验研究。给出了各类土的最大剪切模量试验结果;采用经验公式对各类土的Gmax/Pa~σ0′/Pa关系曲线进行了拟合,给出了各类土的最大剪切模量经验计算公式中各个拟合参数的参考值。同时,总结了拟合参数的参考值随粘性土的液性状态或砂性土的密实度变化而变化的规律。更多还原

【Abstract】 The maximal dynamic shear modulus of recently deposited soils in Nanjing city and its neighboring area are investigated by the test results of resonant column apparatus.The Gmax/Pa～σ′0/Pa curves of these soils are fitted by expirical formula.The reference values of fitting parameters in formula are given for different soils under different conditions.Based on the test results,the variational rules of fitting parameters for the same soil in different conditions are summarized.更多还原
