Experimental study of stress-strain characteristics of stabilized silt

Uniaxial and triaxial tests are performed to study the stress-strain characteristics of the stabilized silt by stabilizing agents.The stress-strain curves of uniaxial and unconsolidated-undrained triaxial tests are analyzed;and the influence of age,mixture ratio,and confining pressures on the shape of curves are discussed.Uniaxial stress-strain test results show that the latter part strength and deformation characteristics of silt change small and with the increase of stabilizer amount,the curve of uniaxial stress-strain changes significantly.Triaxial stress-strain test results show that destruction of strain and stress damage shows a partial positive growth trend with the increase of stabilizer amount.When the curve at high confining pressure it shows weak softening type,when at low confining pressure it shows softening type.
