| Abstract: | Light heterogeneous soil mixed expanded polystyrene is a new kind of fill materials. The test studies are very scarce in China, In present study, based on unconfined compressive tests, the relationships between failure strain and compression strength, and between deformation coefficient and compression strength are analyzed. And according to one-dimensional consolidation compression tests, yield stresses and compressive modulus under different conditions of mixture ratios are obtained so as to provide reference for the application in engineering. |

| Keywords: | light heterogeneous soil with expanded polystyrene failure strain deformation coefficient yield stress compressive modulus |
