摘要
通过室内动三轴对不同级配、不同粘土矿物成分、不同粘粒含量、不同干重度的重塑土所进行的系统试验,得出不论所含何种粘土矿物。也不论干重度及粗颗粒级配如何,抗液化强度均在粘粒含量为9%左右最低的变化规律。
Based upon indoor dynamic triaxial compression test a series of tests are carried out to study the liquefaction characteristics of the re- molding soil with different gradations,clay materials,clay particle contents and dry unit weight.The results show that the lowest dynamic shear strength is at 9 % of clay particle content no matter what kind of clay materials,dry weight and gradations.
