Study on the Impact of Long-Term Immersion on the Shear Strength of Compacted Lime Stabilized Expansive Soils

Abstract:

To offer or predict the shear strength of compacted lime stabilized expansive soils after long-term immersion for the slope analysis, the paper carried out direct shear test on the compacted stabilized expansive soils after different immersion time. The test results show that long-term immersion has significant impact on the shear strength of the lime stabilized expansive soils, the shear strength reduced sharply after soaking, but the shear strength tends to a stable value about 60%~70% normal strength while soaking is longer than 50 days. Logarithm model can well fitted the sketch of φ, c and immersion times within 50 days, which may be used to predict the shear strength of the stabilized expansive soils quickly.
