| Abstract: | Unconsolidated-undrained and consolidated-undrained triaxial compression tests were conducted on the polystyrene lightweight soil with different cement mixing ratios, densities, and ages under confining pressures for the study of the stress-strain properties of the soil and the method for determination of its shear strength parameters. It is indicated that the cement mixing ratio, density and age of the lightweight soil have different influences on the results of stress-strain properties and shear strength indexes of the soil in triaxial compression tests under unconsolidated-undrained and consolidated-undrained conditions. |

| Keywords: | stress-strain shear strength confining pressure |
