| 摘 要： | 本文通过多种土类的共振柱试验实测剪切模量,建立与振动三轴试验的液化剪应力、静三轴试验的非线性变形参数、膨胀土的含水量等相互关系。检验了用共振柱试验确定液化剪应力的可靠性,用共振柱试验来确定静三轴非线性变形参数值是可行的,提出了用现场波速法试验结果确定土体膨胀性大小。

| Abstract: | Established in this paper are the relationships between shear modulus obtained from resonant column testing and shear stress at liquefaction from dynamic triaxial testing,shear modulus and non- linear defarmation parameters with static triaxial shear testing as well as water content of expansive soil.The accuracy of shear stress at liquefaction and reliability of nonlinear deformation parameters determined from resonant calumn testing are examined.It is suggrested that the in-situ wave velocity method should be used to measure the expansibility of soil. |

| Keywords: | shear modulus shear stress at liquefaction nonlinear deformation parameter expansbility |
